User Interaction Consultation/start proper maintenance of the really good existing stuff.

Stop changing the encyclopedia to a social network
A lot of effort by the devs in SF seems to go into unwanted, and explicitly anti-policy facebookisation efforts, like Flow, Gather, MV and some other stuff. The wikiverse is explicitly not a social network, so while interaction to make discussions about content (and unfortunately sometimes policy) are wanted, and should be improved, dumbing down the system to get it more like social networks should be discouraged.

Keep the main goal in focus
All projects are about content. Discussions should be about content (and sometimes about policy). Facebook is in no way any model for anything here.
