I remember one time Matt Cutts talking about the user experience… about how they were focused on delivering what they think the user would find.
For some time I had thought seo chat was pretty much good for nothing. The user experience had been so hindered with advertising, popups, and other things that REALLY SUCK for the end user.
A bit a go Seo Chat started applying nofollow attributes to there users posts in a effort to alter the natural flow of links and other stuff. Many people thought they were trying to maintain there own PR and what not.
I GUESS IT DOESNT MATTER NOW LOL
