What is it with all this talk about quality members? As opposed to non-quality I suppose. People tossing around numbers about 20 or 10 people who are good or legitimate or who "get it".
I agree that people come and go all the time. Sometimes they come back and sometimes not. Who cares that much? There's always still plenty of good information and reviews to be had. I haven't noticed any real slowdown in reviews, which are the main thing for me.
As far as bad eggs ruining things for everyone, well, everyone acts like a jerk sometimes. It's not just the new turks either. Plenty of old guard around who are obnoxious sometimes. I think the best thing people can do is take from the boards what works for you and try to ignore the rest.
