Ask HN: Is there a self-hosted alternative to Facebook groups?
With similar features like moderation, anonymous posts, public/private groups, etc.
It's a very big hurdle to overcome. The best way is to generate vibrance within a niche, promote it in the right places, and to really cater to users, and then maybe after years of losing money and being stressed, you'll have something notable, provided it hasn't devolved into just another huge clone of Facebook by then.
I'm wondering if a third party groups app that supports Facebook auth could be a gateway out of Zuckland while leveraging the Facebook network effect.
