There is a common denominator in all the blogs and forums I've seen get off track. I'm sorry to do this because it's not what the site is for, but...

I sent a pm in one such instance (think pretty much everyone knows what I'm talking about) as a way to privately debate an issue I had about numerous comments (not just that one) regarding who should and who should not be allowed on this site. It makes a lot of people feel unwelcome, and if you don't think a blogger belongs on this site, then how about you just don't respond publicly to their blog.
