Maybe you have some mistakes. Nothing has happened. Anyways, some sites may down to PR0 because they are banned by Google.
I don't know I have seen a couple of people through out the fourms saying they have had pr updates, but the majority have reported nothing. It may just be a minor update.
Ban any fool who starts a PR update thread!!!!!! Google updates PR daily for its employees......what to hell is so hard to understand???? Toolbar PR is a drug most people seem addicted to
Instead of just posting to boost your post count.... read the very informative post immediately before yours...
Every day someone posts a thread. I suggest people read the thousands of other threads about PR update first, and keep adding to those. I usually don't even bother adding comments to these silly threads, but I felt the need to this time.
my site rankings are changing again and again. I can feel there must be something going on with google search rankings and page rank.
I had a couple of domains update, nothing major but one site PR0 to PR3 and another PR0 to PR2. Something minor did happen.
Your post were in the second page, The option to comment is over the first page as well, The possibility to read your comment before posting was low.. The info you gave isn't informative at all, It is just your opinion that I might even agree with because it makes sense. The bottom line is that your main website rank can change every day right, But the summary we can see each few months, That's why I assume peoples open those threads.
