As for pagerank, here goes: Goggle ranks sites 0 to 10 - Goggle of course being a 10. A good site today is a pr5. To be able to watch pagerank you need to get a goggle toolbar.

So a portion of the internet's value is controlled by goggle and when goggle decreases the pagerank scale as it did two months ago hundreds of millions of sites lost considerable value.
