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.
Interesting. As I mentioned in another thread Matt Cutts himself asked if webmasters would be ok with Google helping us out by being selective towards the nofollow attribute. At the time my understanding was that some websites shoot themselves in the foot with nofollow, it's a relic from the internal pagerank sculpting days, and that Google could ignore it when it benefits the site(s). Thinking that question through one could only come to the conclusion that Google would ignore nofollow when Google trusts the site being linked to already, and here the question is raised again under 'similar' links.
More on topic: Has anyone used the 'similar' site/page results as a template for contacting sites to see if a backlink might make sense? Google is telling you the sites/pages are similar so it's hard to ignore that these would/should likely share many connections.
As far as I can see the pages are rarely linked together but my broken link scanner might not be the best tool to get a definitive answer on that. I do know that none of the first 50 similar sites link to mine according to GWT. If the similar sites feature is essentially our roadmap for where links might belong I'd like to know but documentation is hard to find.
