I like your list of ideas, but I just want to bring up one point:

Sometimes the only way to get an insight to the thought processes of the busy & insightful people of the world is through something like twitter, because they don't have time for anything else. Certain subcultures of twitter can be fairly positive despite the lack of moderation tools because the community is small and not a current political hot potato.

That is something I wouldn't want to lose.
