Lately I’ve noticed more and more of my favourite sites, many which are sites that have had very high PageRank in the past, showing no PageRank whatsoever - not zero PageRank, mind you, but null PageRank. I haven’t seen PageRank be updated for any of the sites I frequently visit for quite some time, either.

Is Google phasing out its public display of PageRank for any given site? It’s clear that Google must still be updating PageRank internally, as it is a crucial part of the algorithm they use to rank websites in search results. Link-back updates have occurred recently, supporting this theory.

So why is it that PageRank seems to be getting stale, and in some cases is just plain broken?

[Update]
I just noticed that Jason Calcanis over at Weblogs Inc. has been wondering the same thing.
