It would be great if there was a way to reparse data or to remove rogue data.

I have some long-term issues regarding URLs where I changed permalink structure, and a few cases where the data stored was totally off.

One example is a post with 10 comments, which Postrank counts as 204 - that throws off lots of trend data for top rated posts, that ultimately also kills readership by people using Postrank for filtering in Google reader, and makes the top posts widget display meh posts.
