Absolutely no change, just updated PR's of my directory list. I think only crappy ones might have got penalized.
And i have to add more information about the PR update that i think is going on. My inner pages got some page rank (PR 3) So, something is really going on....
You must be doing something right, because I don't think most directories are going along this strong Its pretty interesting because in the searches I've done there are very very few directories that still have PR and actually review submissions.
Google keep changing their pagerank formula, and the way they give pagerank to sites. Even if you get more backlinks, your pagerank still dropped.
In my opinion, i don't think all directories have lost there PR values.. instead some of them who abused their directories might lose there PR
You have a nice website indeed. I checked some directories and find some of them lost PR from PR 3,4 to N/A. but I think this will be recovered days later.
I also notices the changes of Directories' PR. I also think that google really pay less attention to directories now.
