That's good to see, as I've dropped a number of links to "dodgy" sites for safety reasons, so it seems like we're getting close to the point where it can/should be used more widely, for safely interlinking domain networks for example.
Matt Cutts had this to say:
"As others have noted, if you're going to sell text links that pass reputation/PageRank, the way to do it is to add rel=nofollow to those links."
"The rel=nofollow attribute is the correct answer: any site can sell links, but a search engine will be able to tell that the source site is not vouching for the destination page."
You can read the discussion here, you'll need to add the http but not the www:
