Another SEO thing about Page Rank and Google!

Reading the blog post PageRank sculpting it looks like dofollow and donotfollow links are not very helpful any longer at least not if you look at what the guy explains here.

More than a year ago, Google changed how the PageRank flows so that the five links without nofollow would flow one point of PageRank each.

It is always a matter of estimating the waight of what the guys from google are publishing... no one really knows what they do, personally I would still use DoNoFollow links to avoid people spamming my blog.
