James, I have to agree with Shenron. There is no evidence to support what you are saying. The inner pages of almost every properly designed web site do pick up PR as along as the the linking page has PR and the the linked-to page has not been penalized by Google. Very few web site have external backlinks leading to most inner pages, yet they still pick up PR.

Perhaps EzineArticles is not the best example to use. Very few inner pages in that site have any hope of picking up PR from the home page because there are too many links on the home page, which dilutes the PR that is passed. Plus, the links from the home page may not exist long enough to pick up PR and articles quickly get buried way too deep in the site. A well-designed site with a good linking structure (such as WordPress) does pass PR to the inner pages, but if I tried to add hundreds or thousands of articles to a WordPress blog every day, it would experience the same difficulties as EzineArticles. You also have to consider that EzineAricles is a huge repository of duplicate content. Without links back to the articles posted on EzineArticles, Google has no way of knowing which article is the original and they therefore get wacked with a PR of zero or a gray-barred PR.
If Google follows through with what Matt Cutts said a few months ago, toolbar PR will disappear some time this year and it will become a mute issue.
