I agree that PR is just a reflection of how your link building is working, but surely i you have equally (on page) optimised sites, one being a PR 2 and the other being a PR 6, the 6 will win in the SERP's.

So I don't see how you could say it means nothin these days?

Assuming this is right though, what would you sy are the most important optimisation points at th moment?
