Life would be bland without differences of opinion!

To be clear I don't subscribe to the notion that nofollow links carry value, in fact they specifically don't by design, but I do suspect that G is capable of ignoring the nofollow in time if they determine the link to be a good one.

In other words I believe there is a possibility that the nofollow tag can eventually "fall off" in the eyes of Google. This would of course be the exception, and perhaps only done by a human editor, but Matt Cutts has stated that G is able to control pagerank flow right down to individual links on a page and this would be an excellent use of such a tool on a site that has gone overboard with nofollow. I do have several examples I'd love to link up but I think you're right about blogs, I haven't seen one I'd suspect in a blogs comment section yet.
