I've read tonnes of forums. Had a Reddit account 3-4 times.
Also been posting a little bit on Angry Metal Guy, but that site is so lame. Unicorn memes are so funny!
Especially if it's the only joke every dork on the site is posting for 5 years straight. Barf. And the combo of plebbiness (is that a word?) and snobbishness makes me angry.
Basically, most forums don't really have a culture that I wanna take part in.
Reddit always manages to make me run away screaming after 2 days for whatever reasons, no matter the sub-forum I'm posting in.
I think MusicBanter is just the right mix of relaxed & nerdy without more drama b.s. than you can move around it if you wish to. Most of the time
