Google have just updated their Directory from DMOZ ... took them all of 7 months
I should have been more carful with my words - they are updating ... some categories are bouncing between the new and old version - the updated directory probably has not been propagated to all data centers yet.
PR in new version of Directory is interesting. I have a 6 week old PR 0 (according to toolbar) site with 3 x PR3 incoming links. The new version of the directory (its not in the old) is showing a PR of about 2 (I will take it!!!) - so could speculate that the PR in the Directory is different (? more up to date) than the toolbar???
