Lost my Google PR2

[crazydog]

Hi there
Just got curious reading this discussion. Some of you writes that PR doesn't matter a thing others that it matters but is a secondary feature. None of you really talk about what PR is and what it influences or signifies! So my question is how would you describe Page Rank - what defines the Page Rank and does it have any uses like for example getting higher faster in the Google rankings or just providing more juice in your outbound links? Or is it just an empty concept with no meaning?

Best regards
