PageRank and the use of nofollow

There's an interesting discussion happening on Andy Beard's Blog about changes to Google's PageRank algorithm, and whether or not the nofollow tag still works to preserve link juice. If you're using nofollow in this way, you need to read this post.

Unfortunately, the exact nature of the changes and their impact is still unknown. I'll post about this again, once the impact of all this is better known. Stay tuned.
