Could you be more detailed about this particular
A site, I looked at, referred to under related:widget.com , had some links shown in the results, with "no-follow" in the code of the referring site. Google seems to have ignored the do follow, in attributing a relationship to the originating site. Hope that makes sense.
I don't know how extensive it is, but folks might want to check it out. Especially as Google is coy about showing off everything that it thinks or knows about your site. It's probably not an issue in terms of false positives elsewhere, but who knows. I guess this might be a question mark in terms of +/- or just neutral influence. Who knows.
