What I like is that it's small, but active. We only have something like 10 real regulars or so, but we manage quite a few posts between us, and over a rather large amount of subject matter, as well.
I like that we don't have too many rules about language, or how we must act, as long as we're being reasonable.
I like the people who post here (you guys are all cool, unlike quite a large portion of the internet).
Hell, I like that you guys actually know how to type properly.
Essentially, s.net is the antithesis to everything that you commonly find on other forums. I mean, pretty much every other forum I've been to recently has been filled with idiots (who either can't type better than a drunken cat, or have no clear perception of the word argue, and take everything personally, whether I intended for it to be taken that way or not), essentially dead, too based on one subject, or so full of people that it's hard to really tell a regular from a new member other than by post count, which isn't always an indication (anyone remember snowcrafta?)
