Yeah, agree with the people who say that pr drop can happen anytime, it doesn't require that massive pr update to happen. One of mine went down from PR3 to PR 2 during the last week. And oh, I'm tired of these countless "pr update" threads
It's always changing and updating, only the toolbar in your search bar will update, I have noticed PR is in points (.) like 1.7 0r 2.8 etc and mine vary weekly .... I am not really fazed by PR at all though and I believe that it's over rated - just like Google and associated Google products . Everyone needs to realise that Google isn't god and Google needs to realise it can't keep trying to be the sherriff online - they can't police the internet like they try to do.
google doesn't even do it correctly anymore - they don't want people to use the PR system to make money so they penalize mass sites only one of my sites lost pr from 1 to a 0 so i don't care much - its worthless anyway, google is failing lately
yeah its not really an update, rather Google penalized some sites... (who probably sold links or was engaged in blackhat stuff)...
