In my opinion, things were sliding downhill for a few months before the sale. Probably this related to the impending sale and lack of interest. Those who have been around for a long time might remember how the forum terms of use were being ignored by the management and the whole forum was going downhill. When the new management started trying to enforce the rules, it was a bit haphazard to say the least. This resulted in some people getting well deserved bans, but some continued to get away with too much, and others were running into hastles for no good reason. So many members finally left.
Again, in my opinion, I think the present forum is being run from the management side a lot better than it was a year ago. The editorial and news content is fairly poor, and I have my own complaints with it, but I can get solid news from other places and debate such here. Also, I sometimes find someone with a problem that I can help. Not often, but sometimes.
No website is going to satisfy everyone, you, me, or someone else. The trick is to put together a combination that does well overall. That said, no one is forced to stay around. Anyone can come or go as they please.
