Hoping someone can clarify. Isn't the PR and linkjuice of web 2.0 property only coming from the home page domain? like blogger.com or hubpages.com? For instance, Hubpages.com has PR 6, but if I make an article, it will be published as hubpages.com/hub/mypost and then there is no PR down at this level to pass along if you put a link in. I think the same thing goes for all web 2.0 sites. So how is PR juice transferred along??
