It seems like forever that I've wanted either Facebook or curated comments on my local paper's site, SFGate.com
I'm at the point now where I won't click on a link or read a story on SFGate -- I will go an seek out another news source which carries that story if possible. The net effect of having such a cesspool of comments beneath whatever I'm reading is that it makes me I'm participating in a community of scumbags.
I'd rather read the Economist or NY Times, where the comments seem informed.
