This is the second car forum I have ever been a part of and I just joined. I used to own a Cobalt SS and was a member over at CobaltSS.net.
From my brief experience here, this is a much more mature crowd who provides informative information. This site doesn't seem dead to me, they're just aren't a bunch of youngsters insulting each other and creating arguments. The threads/topics here are of substance and there is not a lot of clutter to get through to find what you are looking for.
