The BBS is all about socialising and having fun, at least in General. As much as I try to put a chatty, informal and funny tone on a lot of my longer posts, it's a fact that you can enjoy a short post much easier than a longer one that might be horrendously stuffy, ambiguous, etc. It's really just a style that fits me, on a BBS that I happen to enjoy using a lot. If every user was being forced to make longer posts under threat of being banned or deleted, the user base would probably dry up pretty quickly. Even those of us that love reading would get tired of it.
I think a lot of it is about posting in threads that you actually have an active interest in, something I picked up from a certain mod some time ago. Looking through my previous recent posts, you'll see that a lot of them are on similar topics. When I see a thread about the upcoming literature features for example, I get all excited (yes) because I'm passionate about writing. I also have a very smug demeanour; I poke my nose into places where it's not really needed (or wanted). I'm looking at you, open discussion thread...
As Poozy said, some may find me, or another user that makes drudgingly long "mildly annoying" (I laughed) posts. As I've said time and time again, I think the BBS community is far better than most give it credit for. After all, that's why most of us keep coming back. I think things are largely fine with what goes down day-to-day really. Hmm.
