Maybe they left the new guys at work. Someone tripped over a plug, and BAM! Instant panic across the web.
If PR as deceased, it would have a affect on a lot of webmaster who have designed websites for information about G PageRank. Just searched google and they is a few thousand website dedicated to PR with pagerank type domains.
I wonder how text-link-ads.com, linkadage.com, etc. will run their businesses if this were true and toolbar PR really is dead?!
Are you using Firefox? Seems PR has disappeared using that browser but using IE PR is still showing..
They have obviously been doing something about 302 redirects, just what is the question... http://forums.digitalpoint.com/showpost.php?p=188743&postcount=12
Hmm that's weird - maybe a US issue then? I'm guessing of course but here in the UK, on my websites I can still see PR using IE, but not Firefox. Seriously though folks, I'd not worry about it unless your rankings start dropping! Concentrate on getting more links to your website, and researching your competition, from experience you can't go far wrong.
