I'm bumping up this topic so that it doesn't fall by the wayside. There have been a couple questions already about this (here and on Area 51). I'm starting a new thread with the clear goal of formulating a clear plan to get this site in gear and to give us a clean slate in which to work.
I'll post an answer that is my idea to move forward for folks to vote on and for others to propose their own. That will make this a poll-type question, but I think it's time we put all of the ideas in one place and get a consensus on what to do next.
I think we are pretty far into the beta period and the health of the site has some serious issues, so speed is important. But please take the time to carefully read, propose, and vote.
This site has a ton of potential and I think we all really want to see it succeed. Let's get this site out of beta if only so that we can see what design @Jin and his gang can come up with for a site about design, a challenge if there ever was one.
