Google's pagerank?
I recently installed the indispensable Google browser toolbar and while I knew about google's pagerank feature before installing this feature, I notice the pagerank of each site I visit is displayed. My site has a pagerank of 5/10. What is the significance of this? Is achieving a higher pagerank easy? Hard? I read google's info about pagerank and it is rather vague, it merely implies link popularity is important which I already knew.
I also notice there is a feature to vote for or against any website you visit by clicking on a smiley face or a frown on the toolbar. Does anyone know what voting for or against a page here affects?
