did google did a PR update a few days ago or not?
 

^^^^^ title. Nothing changed, my blogs PR shouldve rised like hell

No they did not, allthough it was speculated and reported on a few boards that movement had been seen, there has been lots of movement last several days in the serps so we can just watch to see whats up, allthough i suspect a pr update very soon.

thanks for the info

Something happened, because I see different PRs now. I use the "old" toolbar, not sure if that is why?

Nope.. backlinks will update around 11/7 (+- a few days)
