I feel the same. The quality of the users has been going down lately. I still enjoy the forum and all, but I miss the good ol' days.
I feel like it's not actually the userbase decreasing in quality but old users decreasing in naivety; as us older members start realizing we're spending our time surrounded by a bunch of kids our perception of the userbase changes. I don't mean any disrespect to current forumers, but I remember when I was thirteen or so and when I'd read stuff here I'd learn so much stuff and be impressed by others. Now I'm eighteen, and the forums have lost that glow. They're still an interesting place for conversation, though.
