Alright, no it’s not. For those of you who are watching your PageRank using one of the myriad of tools available (SEO Quake, Search Status, etc.) you may have noticed that the bar is grey. Google has not discontinued PageRank, they’ve just moved it’s reference URL and most tools have yet to adapt. You can expect updates soon from most of them I’m sure.
This issue was first spotted by (go figure) Dave Naylor.
So rest easy, we’ll all have a little green bar to continue to stare at.
