It's always updated. The toolbar isn't, it is an estimate from archived data which Google basically said they may not keep updating it. Since most of DP are affiliates I can see why you all would be so concerned. Just keep an eye out there will certainly be new threads posted when it updates. It just updated not too long ago, so it may be awhile.
I am going to venture out here and say what about Googles new algo, the question should be not when but if PR will change with the new algo coming.
I guess I'll have to wait a few months then... I do disagree though about those saying PR is useless. Granted it won't bring me traffic or clicks, but it does give me numbers and stats which I can bring to advertisers and say "look how popular my site is, Google ranks it very high!".
