Page Rank is all about getting links from other pages with a higher ranking than your own which then boosts your own ranking, but how did Google first start this process and with which sites? The problem is that how could any site have gotten a higher page rank if all sites first started out as a PR0?

It's a bit like the chicken and the egg scenario, which came first? My thoughts are that Google must have made some decisions about assigning page rank in the first instance.
