Just checked digpagerank and I'm showing PR on 3 datacenters where I had none (new sites since May) for www.floridabassfishing.us (PR2) and www.floridabasslakes.com (PR3). It's definitely going now!!!
I am definitely seeing PR changes going up and down. Up on new sites and down on some old ones. No old ones going up yet, but do have some holding same PR
