It's my understanding that pagerank isn't passed from page to page. For instance ezinearticles.com, squidoo.com, blogger.com, etc. has a high ranking for the homepage, but for the individual articles or blogs the pagerank is 0 most of the time.
Is there any advantages to getting a backlink from a high pagerank site say ezinearticles.com from a page with a 0 pagerank (your article) verses any other website with a 0 pagerank. I'm not talking about getting traffic from the article itself, but the link itself.
