How to do and make PR3 to PR4?

Hello, everybody, How to do and make PR3 to PR4 for my site? Could anyone help?

To be PR3 or PR4 just requires that you have an appropriate number of incoming links passing an amount of PR that puts you into that range.

This turned out to be so easy to do with meaningless links that Google now almost totally disregard the PR that they calculate when working out where to put the page in their search results - despite their having access to the raw PR data and not just the almost completely meaningless single digit number that they convert it to for publication.

Does PR really matter anymore? Seems G is more social oriented and “user specific”. Overall page ranking means little.

Do people agree with this?

As felgall seems to have answered the question in full, I’m closing this thread before it becomes a magnet for fluff and misinformation.
