It's most like 4 out of those. Although a mention needs to be made of the new people that seem to appear out of nowhere an pretend like they've been here for ages to fit in. Once they start pretending they understand the fogey jokes, they really should be banned. An also the uninteresting people that stand out so little, you're barely aware of their existence, yet they complain about other people not making worthwhile interesting posts, an how their making the place go downhill.
