For anyone who complains that the site is dead, I have a serious question...do you have a job? Friends? School? Anything else to do with your spare time?
I usually log on in the evenings after work, and there are always at least 300 new posts, most of which I don't even bother to read because it's just too much. A lot of times the interesting topics, like the gun control thread, have pretty much been beaten to death with every point of view imaginable by the time I see them, so I don't bother to post.
If you are that bored, read through every new post, there's bound to be something that catches your eye that you can think of a response to.
I will agree that a lot of the topics have seemed kind of boring or repetitive to me lately, but that's just the way it goes when you've been a member somewhere for awhile. I can't imagine there's anything left to say in the AB/TB/DL world that hasn't been said somewhere before. Sooner or later, someone will post something you find more interesting.
