Some of us are still here.
Yes, there has been enough trolling on all sides to make some just give up.
I'm still around because every once in awhile (and believe me, it is rare), somebody will have an intelligent question based on actual facts with real supporting evidence, or someone will provide an answer with real thought and evidence.
Damn rare, mind you, but it happens.
And YES, I DO miss YAC though I frequently disagreed with her, because at least some of the time, she had good sources for why she thought the way she did. A lot of her arguments were well thought out, coherent and articulate. That doesn't mean I agreed with her, but she occasionally made me think and she FREQUENTLY made me read.
And of course, some answers are just funny. I don't find trolls that funny (they are usually just pathetic), but we occasionally get good/useful answers that leave me laughing.
(And yes, the reCaptcha stuff is getting really annoying)
