Tedsters results may show that links are not followed, but tests and research I have read (and seen in my own projects) say otherwise. I am open mined about the whole thing, but I am loathe to argue with an eminent SEO like yourself which is why I have prefixed pretty much everything I have said with either "in my opinion" or "in my experience"
It is afterall, all I have to go on. :)
In the end, whether the link is followed is actually an irrelevance, I use it for it's ability to mould Page Rank and in my experience, it works pretty well.
