Google doesn’t like this blog!

A PR update was in the works and I guess it has happened. And unfortunately it seems like this blog PR has dropped and dropped straight down to zero from a PR of 5.

I’m totally clueless how this has happened and am hoping this is only a transition.

Or will I have to wait for another three months?

Anybody have a clue on what I should be doing to get this straightened out?

Update: Seems like this is considered to be normal. Atleast according to reports from Blog Herald and zz Online Marketing.
Update 2: Matt Cutts confirms.
