I'll be happy to comment on Yahoo. I've been there since 2001 when my work had us telecommute and chose them for email. I used to love their news aggregate, but just like everything else in MSM, it's been taken over by bloggers and tweets and has a new uneducated, racist audience.
I have been trying to defend and argue and debate as much as possible. Not on Twitter, since I don't have it and it seems like it's a 24/7 crazy place. But I'm on Yahoo, Variety, NYT, LA times, Washington Post-respectable newspapers and YouTube. Mainly for the casual reader on the fence.
I use Facebook, but except for a few forums I'm a member of, not sure where else they talk about it. I'll be happy to comment on Facebook if anyone needs help or points me in the right direction.
