It seems Buddhist Geeks, the guys producing the famous podcast but also running the BG community on Google+, had no success in getting enough revenues in order to finance the team. They announced the community will stay up for the next few months but they prepare a new project, BG Dojo.

One of the issues they mention is the fact that the community primarily engages in peer2peer learning, which means that qualified but also unqualified people 'teach' - which causes legal problems and increases their overhead even more.
It will be interesting to see how BG Dojo will try to solve this.
