I wish I had known about this place sooner.
Sorry to hear everyone's moving on, but I guess everything has it's end.
I don't really think that's the case just yet.
It really seems like people still check these forums and still reply, but no one bothers to start new discussion or anything like that. I understand it because I'm part of more active forum too, so it's difficult to want to come here and start topics. But the thing I enjoy most about this place is the people so maybe I'll start making more. We all should.
I read your post and tested your hypothesis I made 2 topics to see if active discussions could be initiated.
In Off-Topic I started a topic about JCVD's latest flick Universal Soldier (and the series in general), and then for Gaming Forum I made a topic on Super Street Fighter 4. I think both topics were discussion worthy and not discussed on the forum before but appropriate for our demographic, yet both topics discussion ended with in the first day, this post is made around 72 - 96 hours before the topic was created.

This forum is now a very
small community. Trying to discuss very specific things is never going to make a busy thread here because anything that interests less than 50% of us is not interesting many people at all. A good example is myself: I have never watched the Universal Soldier movies and I don't like Street Fighter so I didn't click on either topic. I wouldn't on a busier forum either - it's just that me not posting in a thread makes more of a difference here.
We all know this place isn't as active as it once was, but the point is that the people who still come here probably won't be leaving anytime soon. Your 2 threads created 8 posts that wouldn't be here otherwise. If we all did that, it would be a lot more posts everyday. If you really want more replies though, I'd suggest more open questions.
