http://www.facebook.com/ has a PR of 9
http://www.facebook.com/login.php has a PR of 8
This rule applies to the majority of sites (sub pages often have a lower PR than the root domain)
Here is the problem
www.site1.com has a PR of 10 (not true)
www.site1.com/article.php?id=12345 has a PR of 0
If you take that, and apply it to any ezine article directory, how are you supposed to get any kind of PR ranking on your articles???? What good are those sites if only the root domain is worthy of a high PR? are there any article directories that get your specific article a PR above 0, or linked to from their ROOT domain (at least)???
Maybe I"m just confused, but I dont see how posting your articles on a directory gets you any kind of a high PR for that article
