Now suppose you have one site and you are providing good services and good content to read so people always comes.

PR importent for that site which site has content For example you have directory, article site and forum with good PR then people come on your site to get backlinks because of your site have good PR.

You have PR 5 article site then people of course come to your article site to submit articles so they get some boost on your site.

In short your site have PR then you get more traffic. General public don't understand what is PR so they visit your site for good stuff. But webmasters visit your site only for 2 reason. If you providing some thing new or your site has good PR and traffic.

Thanks.
