What is PageRank, and why is it important?

Rather than boring you to tears with techno-babble, how about a nice, simple and clear explanation about PageRank?  Yeah, I thought so to :D

What is PageRank?

Short Answer : A link based metric meant to represent trust/authority.
PageRank (PR) is a method developed by Google as a way to rank a URL based on the volume of links to that URL, and the trust/authority/popularity of the linking pages.

Do +1's affect PageRank?

Google +1's affecting PageRank?

This should be a fairly quick one :D

Since the launch of the +1 button, people have suggested (or even claimed!) that it affects Ranking.  A lot of people went so far as to state that a volume of +1's would even increase a pages PR score.

It even reached the point where sites like Mashable had posts about it.

So, as it deals with G+ and PageRank ... I thought I'd cover it.
