Dan Gillmor's Bayosphere citizen media project has been acquired by Backfence, a Vienna, Virginia based company that intends to use local communities to generate all online content and sell advertising around it.

Bayosphere, which was launched in June 2005, has close to 100,000 unique visitors per month. It has become a lively forum for debate on Bay Area issues, as well as a home for Gillmor's popular blog on technology, citizens' media and social issues. Gillmor announced in January that he was stepping away from fulltime participation in Bayosphere to concentrate on the Center for Citizen Media, a think-tank he founded in cooperation with Harvard University Law School and the Graduate School of Journalism at the University of California, Berkeley.
