I've been wondering why my Google Buzz wasn't linking up with Superuser and Serverfault. I got a pretty good suggestion at webapps.stackoverflow.com. In short the theory is the
"rel~=nofollow" throws it off. I'm wondering if it is appropriate to require a reputation of 2000 before the nofollow tag is dropped from the profile?
Google could certainly fix this on their end, but it seems as a copied profile should just carry over the dofollow link so Google makes the XFN for Buzz. Is it possible to remove this instance of "nofollow" or to find a different way to establish non-spammer status other than reputation? I presume you're doing this to prevent spam, rather than as an incentive to get 2000 reputation points.
I plan on using the other sites in the trilogy but I doubt I'll make 2000 reputation anytime soon on them.
I think this is the message that StackExchange is trying to send:
