I have a real grudge with Google. Why donot they make the PR data publically available, say via their API? There are ways to get PR data, via sites such as www.prchecker.info/check_page_rank.php. By not making PR data publically available, google is only hurting everyone.
If I really want to know PR of a site, I do have tricks using which I can get the PR. But well its against the TOS. So they hurt the webmaster community. But then it does not help them any way. When people get PR without API, methinks the server load on google will be heigher. Not that google would be concerned about it or anything.
So why not
1. Make the PR publically available via say its API?
2. If you donot want to do so, why not do away with PR data all together. Use it only internally. Never show it to an outside guy. Or is PR just a way to force you to use goog toolbar!
