Search authorship

I found a description of a very interesting moment of a Google search engine (perhaps not only it) in relation to copyright material, articles.

Quote:

Google takes the original article on the address where there is more weight (PR - approx. Sandwarrior ). If the NY Times publishes an article from your blog - Google will consider that the article was stolen by you, and not from you, because your hamster does not have PR9. That's the truth of life.

This "trick" is already used, if you need an article for the site from free directories. That is, these directories contain articles with a certain PR. You can safely use these copyrighted materials on your site if the PR of the site is more than the PR of the article in the catalog.
