If you've been expecting to get
PR on sites and they still show as PR0, don't worry. This has been an unusually inconsistent update.
I have pages made at the very end of December that have been given PR4. I have sites made in October that show no toolbar
PR (but are already ranking in SERPS) and other new sites that have been given toolbar
PR but are nowhere in SERPS. The sites that are showing PR0 have enough
PR in the links pointed at them to be PR3 or PR4.
