I've always loved basschat. I am posting less now than I used to, but then I used to post on all sorts of topics just because I had too much free time and/or couldn't be bothered to get my work done. these days I try to get more work done and only post on topics i'm genuinely interested in. That doesn't mean the forum's getting worse, i've just changed the way i'm using it.
This kind of thread comes around once or twice a year, and that's proof enough for me that the forum's not changing.
the voting system - I hadn't noticed it to be honest, but I guess this is why there are less threads full of "+1" posts.
