I started researching directories to add my website and noticed a pattern - in every directory the page with links to websites has no Pagerank, while a page one level above can have quite high Pagerank. For example:
In both cases a page one level above has PR5 (sorry I can't post more links due to my new account low rep)
Does Google deliberately do this to discourage us to use directories for links? Does it mean that there is no link juice from such pages?
