Whats the point of PR?

i also think that by paying special attention to the way you link internally and externally on your sites you can maximize the amount of pr you distribute.

This is very important...
also asides the ego thing if you have a high PR index, you can filter the PR through your site and maintain deep pages with a high PR meaning you can link off these to other sites (having opimised all pages for different term - you will benefit greatly from this). Its like building SE niched hubs
