When CoTweet sold to ExactTarget a couple weeks ago, the acquisition price was not disclosed. But an SEC filing put out today suggests that ExactTweet paid at least $8.1 million in stock for CoTweet. That is the value of “securities offered . . . as partial consideration in connection with a merger,” meaning there was likely a cash portion as well. While this isn’t a huge sum, it’s not a terrible return for an initial investment of $1.1 million.

CoTweet helps businesses manage multiple Twitter accounts and use it more effectively as marketing channel. The CoTweet acquisition is now being pointed to as an example of how businesses can be built on top of Twitter. So now we know how much the stock portion of the deal was worth.

Before livestreaming video networks like Justin.TV can become attractive to advertisers, they need to deal with their piracy issues. It’s the same thing YouTube had to go through, except with live video streams. Like YouTube, Justin.tv complies with DMCA takedown notices and is developing digital fingerprinting technology to identify copyrighted video on its network automatically. It also invites copyright owners to police the site directly.

Despite these measures, a casual perusal of the most popular streams on Justin.tv is filled with pirated streams of professional sports, TV shows, and movies. Right now, for instance, you can watch King of Queens or CNN International, taken straight from TV. The company finds itself increasingly under fire for copyright issues. To help it deal with these issues, Justin.tv now has a new adviser, Eric Goldman, the director of the High Tech Law Institute at Santa Clare University and a highly-respected Internet law blogger. Unlike Justin.TV’s very-expensive lawyers at Wilson Sonsini, Goldman will be less constrained in speaking publicly on behalf of the company about these issues. Goldman is an expert on how copyright law is applied to user-generated content. But in many ways live video on the Web is a new beast.

When SXSW sets up its festival, you have to assume they want the best and most engaging keynotes possible. If the public reaction to Umair Haque’s interview of Twitter co-founder Ev Williams is any indication, they failed. Badly.

I wish I could take credit for the title here, but it is all Mike Monteiro, appropriately, by way of Twitter. Below, find a sampling of some of the other best tweets about the keynote. As someone who was in the audience, all seem pretty accurate.

We are just starting to announce the first speakers at the upcoming TechCrunch Disrupt conference in New York City on May 24 – 26.

TechCrunch Disrupt is a three-day, single-track conference and startup competition to immerse you in the debate about what’s changing in media and technology right now, what’s causing it and what we need to do about it to survive and thrive in real time. Join 2,000 or so of your closest friends to talk about what’s most important in the collision of technology and media.

Half of the event is a March Madness style startup competition. We’re sorting through hundreds of applications to find the most interesting startups launching this Spring. You’ll see live on stage demos, rapid fire Q&A sessions with expert judges from a variety of backgrounds (product, finance, team building, leadership and more) and highlights from behind the scenes mentoring sessions.

The other half of the event will put leading experts from around the world on stage to talk about the stuff that matters most in technology and media. A few of the speakers and experts are listed below. Keep an eye on the Disrupt Blog and Speaker list for more updates.

During his keynote at SXSW this afternoon (live blog here), Twitter CEO Evan Williams just announced a new “At Anywhere” platform, which allows websites to more deeply integrate the service into their sites. The idea is to offer a more seamless experience to Twitter users navigating third party sites like the Huffington Post and the New York Times, giving them Twitter content without forcing them to jump off the page they’re currently viewing. The details on the new platform are still scant, but this is Twitter’s answer to Facebook Connect, which we reported on back in January.

Among the features:

• When you browse a site that uses @anywhere, people and brands that have Twitter accounts will be highlighted with a hyperlink. Mousing over that hyperlink will show a small box (a “hovercard”) containing their Twitter information, including their most recent tweet (in effect it means you don’t have to click over to Twitter’s homepage to see their Twitter profile)

In an effort to sort out the state of the “Location War” going on here at SXSW Interactive 2010, I have been lucky enough to chat with several people behind the scenes of these mobile location based services. It’s funny to me calling the competition a “War” as everyone with whom I have spoken seems incredibly mellow and down-to-earth but there is a potential definitive moment going on here for that industry. I was able to catch up with Gowalla co-founder Josh Williams and talk a bit about the current state of Gowalla and their mobile app. Standby for more interviews with the some of the competition and a part 2 video of my conversation with Josh.

We’re here at the SXSW festival in Austin, Texas where Twitter co-founder Evan Williams doing a keynote Q&A with Umair Haque. Williams may use the time to talk a bit about Twitter’s upcoming ad platform. Update: It’s actually an “At Platform” called At Anywhere — more here.

Interestingly enough, Twitter saw its first burst of popularity three years ago at this very conference.

Below find my live notes (paraphrased):

New data released from analytics service Hitwise today names Facebook the largest website in the U.S. with 7.07% of all U.S. visits. Google is second at 7.03%. Yahoo Mail is third with 3.8% and Yahoo is fourth at 3.67% (if you combined both Yahoo properties, and I’m not sure why they don’t, Yahoo would be first). YouTube (a Google property) is fifst with 2.14%.

This is the first time Hitwise has named Facebook the top site in the U.S. Comscore still ranks Google the top site by reach at 81% of the U.S. population. Facebook, at 53%, is still behind Google, Yahoo and Microsoft sites in the U.S., according to the most recent Comscore data from February 2010.

We’re in the midst of full-on location war is raging this year at SXSW in Austin, Texas this year. But actually, someone has already won: AT&T.

Yes, despite my concerns, I’m happy to report that the network has been incredibly stable over the past several days. In fact, it’s the best I’ve ever seen AT&T’s network perform — anywhere. Over the past three days I haven’t dropped one call, haven’t missed one voicemail, haven’t been missed any text messages, and the data is flowing freely, allowing my iPhone to actually work.

All naysaying aside, people are pretty excited about Windows Phone 7. Our readers are excited for it. I’d be outright lying if I said I wasn’t excited about it, too. Know who else is excited? The Windows Phone 7 team — but perhaps not for the reasons you’d expect.

With a few years of work finally coming to a head, some of the folks on the Windows Phone 7 team are taking a step back, looking at the fruits of their labor… and leaving. Not because they’re ashamed, and not because they’re being poached by the competition — but because instead of making Windows Phone 7, they want to make things for Windows Phone 7.

Startup Seesmic has perfected the art of developing compelling Twitter clients on a variety of platforms. Seesmic offers a web client, an Adobe Air-powered desktop client, an Android app, a BlackBerry app, a brand friendly Twitter client and a native Windows desktop client. At developer conference MIX today, Seesmic founder Loic Le Meur is announcing a new Silverlight-powered development platform and Seesmic for the Windows Phone.

The new desktop platform from Seesmic is built based off of Silverlight, which is a refreshing change from the buggy Adobe Air platform. The design itself is similar in look and feel to the Windows client, and includes functionality for integrating your Facebook, Twitter, and Linkedin accounts. You can also personalize your background of the app. And the new platform works on both Macs and PCs.

The list of people I interviewed at the World Economic Forum in Davos, Switzerland earlier this year is starting to look like more like a hit list than a VIP list. Two of them have been relieved of their current positions – MySpace CEO Owen Van Natta and now Ning CEO Gina Bianchini. If I were Jeremy Allaire, Max Levchin, Sheryl Sandberg or Evan Williams, I’d watch my back. They may be coming for you next.

Facing competition from recently acquired AdMob (Google) and Quattro Wireless (Apple), mobile ad network Mobclix has been steadily working to strengthen its products and offerings. The startup just acquired iPhone app sales analytics software Heartbeat and announced a deal to offer Nielsen’s ad targeting data into its ad exchange to enhance ad targeting. Today, Mobclix is officially launching one of the first SDKs for iPad advertising.

Apple’s new tablet device, which will be delivered to consumers in a few weeks, poses a tremendous opportunity for advertising. The size of the tablet not only allows for larger ad sixes but ads can also be more engaging and media rich, with the possibility of incorporating video and other interactive features. And these means more revenue for advertisers and developers.

I’m here in Austin, Texas, where MOG CEO David Hyman is introducing the service’s new mobile functionality. This is a major step for MOG, and may be an inflection point in the success of the service. Up until now, users have been restricted to using MOG’s streaming music service on their computers. That’s fine for casual listening at work, but as we’ve seen with the success of the mobile versions of Pandora, users want mobile. And that’s what MOG is unveiling today. Read below for my notes.

Hyman kicked off the talk with some background information. MOG Music Network, the editorial-based site hosted at MOG.com reaches 16 million unique visitors a month. In December, the company launched MOG ALL ACCESS, its streaming music service that costs $5/month for all-you-can-eat streaming music. The company is getting 17% conversion from its 3 day free trial (which is high). MOG, Hyman says, is a music service people will actually pay for. But the key will be portability.

MOG’s mobile applications for Android and iPhone will launch in Q2, featuring on-demand streams, downloads, MOG Radio, your library and playlists, High Quality audio, and a $10/month price tag.

Eric Lefkofsky and Brad Keywell, two of Chicago’s best-known tech entrepreneurs, plan to invest as much as $10 million annually in early-stage technology companies through a new fund dubbed Lightbank.

The goal is to provide early-stage startups with seed financing, ranging from 100k to $1 million and fund companies with up to $10 million on an annual basis for the next 10 years. In addition to investing capital, Lightbank intends to take an active role in guiding and nurturing companies through all stages of growth.

The microfinance model has proved to be a valuable way to raise funds for entrepreneurs all over the country, as exemplified by the success of Kiva. Seattle-based Vittana is taking a similar approach to helping fund education in developing countries by allowing you to lend directly to students in the developing world. The idea is to bring student loans to the developing world through the power of person-to-person microlending. Today, the site is existing its beta period.

Vittana partners with microfinance organizations located in developing countries to donate to students in need of funding. Loans for students range from $200 to $1,500, are then funded by individual lenders, via $25 donations or more, on the Vittana website. One hundred percent of the loans are given to the student. Launched in beta last May, the Vittana community has made over $110,000 in loans to nearly 200 students around the world, who are now getting their degrees. Thus far, Vittana has programs in Mongolia, Nicaragua, Paraguay Peru and Vietnam and plans to expand to India and countries in Africa soon. And Vittana students have had a 97 percent repayment rate.

Ning CEO Gina Bianchini is being replaced as the CEO of Ning by COO Jason Rosenthal. Bianchini founded the DIY network of social networks with Marc Andreessen. But after five and half years at the helm, she is ready to try something new. She will transition to an entrepreneur in residence role at Andreessen Horowitz, the venture capital firm started by Andreessen.

In a blog post, Andreessen (who remains chairman of Ning) notes:

A trio of entrepreneurs who led online advertising technology company Accipiter to an acquisition by aQuantive – which was in turn acquired by Microsoft for $6 billion in May 2007 – have returned to startup life after serving a variety of roles in advertising and sales at the Redmond software behemoth.

Jeff Wood, Guy Taylor and Ryan Treichler are today announced their new company, aiMatch, as well as the limited availability for “early adopters” of its online ad technology platform. In addition, the threesome said they have also convinced former Head of Publisher Solutions EMEA for Microsoft Advertising Steve Perks to join the club.

As Apple goes on the offensive against Android, it risks alienating more and more developers. Today, another prominent developer chose the opposing side. Tim Bray, the well-known software architect and blogger, is joining Google to help rally even more developers around the Android mobile operating system.

Bray is the co-inventor of the XML Web standard, and most recently worked at Sun Microsystems. In a blog post, he explains that he is drawn to Google in part because he hates the iPhone, or at least its closed and controlling environment from a developer’s perspective.

Unless you’ve been living under a rock for the last couple months, you know that Toyota has had problems with sudden acceleration of some of its vehicles. Apparently, the root cause of the problem is still unknown, which is a little troubling to the average consumer. Toyota claims to be doing everything they can to investigate, but that doesn’t seem to be enough. Now everyone and their brother are suddenly product design engineers and have the gall to tell Toyota what to do and how to do it.

Witness this opinion piece in the LA Times by David M. Cummings entitled “Haven’t found that software glitch, Toyota? Keep trying“. Mr. Cummings worked on the Mars Pathfinder project for NASA, so he has some credibility to his name when it comes to software design and product testing. But his opinion piece seems to completely miss the point of the PR nightmare that Toyota is dealing with.
