Hi Everybody,
If you asked me to name the biggest irritation that I encounter when dealing with SEO and links, I’d have to say that it’s the belief that Google’s Toolbar Page Rank is the best method of defining quality. A notoriously tricky little metric, the TBPR has become a very common source of headaches for almost everyone.
Two reasons :

1. Sometimes TBPR checkers don’t work.

2. Many (most) people aren’t really sure what Toolbar Page Rank actually indicates.
