Yeah, it CD has been dead for a while. I can pratictly see a tumbleweed passing by...I really enjoyed CD, as this was where all the meme's come from, like Vinegar Ra, Bro and the quote, "Cool story bro."
Cool story bro isn't actually from CD, but that isn't to say we don't have memes. JAHO, Vinegar Ra, Gears of.... And the in-jokes like witty things to say about strawberries

Now that New Vegas is released, the Fallout 3 boards are a ghost town, and the Fallout Series Discussion board is just plain unpleasant to be in unless you're on the side of the aisle that thinks Bethesda and Fallout 3 svck. If that's the case, it's paradise! The Skyrim board isn't very enjoyable either, because people are either arguing with each other, making handfuls of threads for a single GI update or snippet of info, or trying to get their supa kewl ideas into the game. Oh, and disregarding lore if you don't agree with it, of course, I mean that's practically a sport there.
But Community Discussion has been like this for a while, it's just slightly less active. At least, I don't think I've seen much of a big change. Game discussion threads, relationship threads, tech help threads, threads about a random depressing news story, threads about a random science related story, threads about the paranormal that usually get flamed to hell, game recommendation threads... it's always been the same old same old in Community Discussion, at least as far back as I can remember. Admittedly I've only been here for two years, so I was never around for "the way it used to be" that older members speak of. :shrug:
The Skyrim board is just full of bad ideas, regurgitation of the same threads, and obsessing over what little we know. The sad part is, it'll stay practically the same until release.
I'd have to agree that CD hasn't changed much, it's just some of the people have and from what I've seen, replies are coming slower.
