Settle down ya sillies.
Back when the site was popular, it was for a few reasons. First, FragBU drew in quite a few people. Second, the fact our community was not insane to the point of ridiculousness about individual skill. Third, the forums were just plain a lot of fun to be around and we posted news that was interesting to the community we had. It should be noted, I don't think BU has been "popular" since 2005 and in 2005 the admin team talked very seriously about shutting the site down (and then in 2006 and 2007 and 2008).
I would really like to see interest in BU go up, but there is really only one way that is going to happen organically right now and that is if we start doing FragBU again. In order to do so people would have to make a concentrated effort to show up to play every Friday night so that the server is populated in the server browser. Without that aspect, I just can't see people from the existing (small) UT community ever bothering to find us right now.
Another way to draw people in would be with interesting UT-related conversations happening here even if sparingly. The few UT conversations that have been going on don't get a lot of activity.
There are other things we could do like bring the podcast back (kind of dropped the ball on that thanks to TWD's personal life), post more relevant news and op-ed pieces that people are interested in, etc. but due to the essentially death of the UT community none of these options has a guaranteed chance of doing much right now today. However, I think the one thing that has a decent chance at it would be to get FragBU going again especially with Teamspeak.
