Last night, more new reports of PageRank changes have been reported at the various forums. Again, the PageRank score shown in the Google Toolbar is old, not up to date, and is basically for entertainment purposes only - but people still do track it.
On January 9th we reported the last Google PageRank update. It seems too soon for an other PageRank update to be happening, but anything is possible.
This is either a new PageRank push to the Toolbar or it is still some data fluctuations of the old PageRank push.
