Well I am hoping my site will go up by one, but nothing changed for me.

Not seeing any PR changes here across 40 sites.

Nothing here either.

My sites backlinks dropped

My home page dropped from 3 - 1.

Actually I take back what I said.

I have some software that tracks the PR of my link profile. A few pages did indeed change PR. Nothing compared to what I've seen previous PR updates.

I call this a very minor update, maybe a little house keeping. I'd still expect a full update soon.

seeing about 5 new sites with PR. So yes for me. :)

Is the link: command broken?

I have a site that has good pr and over the last 24hrs the site has been completely graybarred twice .... hope the pr is going to come back ..... there is also something very weird going on in WMT link section

I've been wondering - maybe this is what TBPR updates will look like on Caffeine

I think it is a glitch, all my pages besides home went grey. All my main competitors pages went grey.

If it has updated I am very dissapointed, I only recently started work on a TBPR1 site and have produced 10 new inward links plus 10 more from magazines via a PR campaign. I was definately hoping to go to TBPR2.

Should I be concerned if I drop by 1

No. because the drop already occurred long before it showed up on the toolbar. Also there are only 11 visible values that are possible on the toolbar, from zero to ten. But PR is actually calculated to many decimal places. So it's unlikely that you really dropped a whole point, you may have dropped from 3.002435 to 2.99723.

Not only that, but PR is relative to the entire web. As the web grows and more pages get published, the PR scale gets sort of "compressed" - so the toolbar drop may just be reflecting that and not a problem with your own backlinks.

No so far i did not notice any such PR update.

nothing happen here too.

No I've not seen any update for my sites as well. I know a lot of people are expecting it so it could be anytime soon.
