I am very very occasionally asked why I'm not on The V (an old internet hangout) these days. I can't imagine my presence is terribly missed, but Dave has thrown up a summary of the board that he found somewhere (either on the board itself, or on some kind of nerd forum review site, I guess) that has rather set me to thinking about on-line communities, why I basically don't participate in them any more despite having spent a significant chunk of my 20s in one forum or another, and what I think they lack, and it's a topic I wouldn't mind writing something longer about in the near future, so I'm just bookmarking the summary as a useful starting point.
