Yes, I greatly agree with you. Besides, Page Rank is invisible and very negligible to regular users who do not have their Google Toolbar installed in their browser, especially for IE users. And
PR plays just a very little part in affecting your search engine keyword rankings, and the fact that only Google use it means that
PR is not a factor when it comes to other search engines. However, if you really want to increase your
PR, then all you have to do is to gather as much do-follow backlinks as possible, but without going to the extent of spamming every site just to increase the chance of gaining do-follow backlinks.
