Try Diaspora
If you were the kind of person who might like to see how Diaspora is coming along, and why wouldn’t you, then you can do so at my Diaspora-powered site, Radicle.me. Go nuts. Bug reports should go to Diaspora’s github account.
Why Radicle? From Wikipedia:
In botany, the radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination.
