SourceForge acquires Ohloh to target ads at open source coders

SourceForge, the public company whose properties include code repository SourceForge.net and tech news site Slashdot, announced today that it’s acquiring Ohloh, a community and database for open source programmers. This is SourceForge’s first acquisition since 2000.

Bellevue, Wash.-based Ohloh says it has compiled the world’s largest directory of open source projects and coders (more than 300,000 each, gathered from 3,500 websites). Ohloh also ranks those coders based on the importance of their contributions to major open source projects. SourceForge says Ohloh’s data on open source trends will help it target advertising, presumably for the open source programmers and other geeks who make up its core audience.

Founded in 2004, Ohloh’s funding came from individual investors such as Jeff Clavier of SoftTechVC and well-known open source investor Larry Augustin (who founded VA Research, the company that became SourceForge).

The deal is expected to close in early June. SourceForge and Ohloh aren’t sharing the deal’s terms.
