It looks like they don't have anything else to do.
It was a good, interesting forum in spite of Gene's character flaws because there were a lot of smart, well informed people posting good stuff. Gene's true colors were not well known, or at least they were easy to ignore back then. That insufferable boob Randall didn't come along until the forum was well into its death spiral. There were plenty of insufferable boobs, of course, but they were not "moderators" back then. The begging intensified, the questions about it became more numerous, the defensiveness on Gene's part (along with his tall tales in the begging emails) brought it into sharper focus which caused more people to question his claims, and so on. Anyone with something to contribute got the hell out of there.
Biedny pretty well carried the show, with the help of some really good guests. Gene was actually a pretty decent forum moderator ten years ago, or at least he had more patience in that role than Biedny. It wasn't long, though, before his panhandling was well known enough to cause problems, which he then handled poorly. That situation continues to deteriorate, as seen above. Sad, really. He and Randall have each attracted the other into their lives, and have no one else to blame.
The forum archive remains a valuable source of some good work, competent research, and interesting commentary. Gene, sell it to Nivek for a fair price before you let it go offline. Too much good stuff has already disappeared that way. Do it to save your own contributions, if nothing else. Some of that is well worth keeping online.
