I noticed this showing up for one of my sites a few weeks ago and I'm not pleased about it at all. Doing a check on the sites that google says are similar to mine and I don't show up in their results at all, but plenty of their link buddies/network do. Since I get a few thousand searches per month on brand/domain name, that's potentially a fair bit of traffic being siphoned off to others that isn't being reciprocated.
And it gets better yet...when searching for my domain name (.com), the top ten results are maindomain...domain/cat1...domain/cat2...domain/cat3...subdomain1...etc., and EACH of those listings also have a "similar" link to click with a slew of more websites.
Like, geez, we spend time/resources trying to create/build a brand (and google says it likes brands)...then google still finds a way to hack traffic away from it.
