I mostly hang around here because I'm the only person I know in RL who even knows what Doctor Who is, so it's nice to have people to talk about the whole 'Whoverse' with.
It's also good because this has been a small community, which is pretty tight-nit, which means it's been pretty good because there isn't that constant flow of newtards clogging up the forum.
Oh, and I guess it's my resident trolling grounds.
How specific a focus you want the site to have is directly linked to how ambitious your goals for the site are.
