Why is everyone saying that pagerank means NOTHING?

I am just having doubts. any way lets look towards the future..
Google has been shifting its gear in algorithms all this while and we should work together to exchange pointers and views to keep ourselves updated.

No one knows all. There got to be something that others might know.

 

ROFL not it doesn't. PR has NOTHING to do with pages indexed or with Supplementary index. Please go research why pages get added to the Supplementary index.

PR is SIMPLY a mathmatical measure of how many backlinks you have nothing more nothing less. If you have a PR 10 and every site link to you with "Bob is a noob" and you want to rank for Mortgage its never gonna happen even if your online SEO for mortgage is amazing.
