I just stumbled onto this thread, and better late than never, I just thought I'd put my two cents in, seeing as I'm one of those non contributing members.
Although I can only speak for myself, I come here simply because I love the community and talking to people in the forums about anything, TV related or not. In fact, this is the only "online community" I belong to, so take that as you may.
Also, when I first registered for Rage, I remember trying to contribute to anything I possibly could. Even shows that I didn't even watch. But as time went on, it just got hard. I'm personally too busy to maintain a guide, as well as the other things I HAVE to maintain on a regular basis. And I don't want to take on a guide just to have it collecting dust for months. Not to mention, my computer is in HORRIBLE shape, so horrible, it won't even allow me to create a Facebook.
Again, that's just my perspective on it, but I'm sure a few members on here can relate to my reasoning.
I have to say, coming back onto this site after nearly a year, the forums seem like the aftermath of a nuclear bomb. Back in the day, the post parties would have hundreds of pages PER MONTH. The current post party has been sitting in the off topic forum since Christmas and only has 18 pages. Kinda something you have to question at some point. I know TVRage may not be dying, but I think sooner or later you're gonna have to ask yourselves why a huge chunk of longtime members aren't here anymore, and why you can't get a new chunk to replace them.
