PR sucks if you don't have it and is great if you do. It really is irritating whenever you launch a new site which obviously has a 0PR and have difficulty finding link partners simply because your PR is low.

There is too much emphasis on PR with far, far too many webmasters falling into the 'PR leakage' nonsense and trying to 'hoard PR' by not linking out or wrapping outgoing links in javascript, disallowing spiders via the robots.txt and trying to use the recently introduced <nofollow> tag.

If PR 'leaked', then dmoz would have a 0PR.
