thePlatform, the broadband and mobile video services provider that is now part of Comcast (NSDQ: CMCSA), has acquired assets from San Francisco-based Chirp Interactive, a provider of social media applications…some of Chirp’s employees are transitioning into the bigger company. Chirp’s standalone service will not continue, but its community and content discovery features will be integrated within thePlatform’s media publishing system. In addition, thePlatform, based in Seattle, is now expanding into Silicon Valley, including opening a branch office.

Chirp was founded last year, and had funding from Greylock Partners and Jeff Clavier’s SoftTech VC, and angel investors Reid Hoffman (founder of LinkedIn), Jay Adelson (CEO of Digg), and Dave Samuel (founder of Spinner.com and Grouper). The company’s product, chirpscreen, was a desktop/screensaver based social app, but seems like it never took off and from the wording of the release, looks like thePlatform bought out the assets.

More details in release.
