I recently blogged about a really cool that offers webmasters an opportunity that are buying, selling, or trading links based on PR to determine if they are actually getting what they pay for:
I'm not sure I agree with the nomenclature ("fake PR" to me means PR spoofing with cloaking), but your tool provides a good service (just as any http header checker does).
Nice tool. Does this tool show the real PR that is updated regularly as the toolbar is updated every 3 or so months. If it is then I will use this tool when checking PR. Gutted that my PR is the same as the toolbar though. Wanted it higher. lol
