The day has come finally – people not only deciphere the Google PR checksum algorithm, but also published it for free. That could mean that Google might change it soon – on the other hand – for what? Alexa and Yahoo Ranking numbers are available via an open API... I think it's just the typical Google Buzz Marketing to make the checksum a "secret".

As you all know open-source rocks and closed source and protections are being cracked some time… especially for common interesting things like web page ranking information.

The original posts of the algorithms are here in ASM and PHP, but a pascal version is available too…

Anyway – I guess the number of PR queries will increase and Google will let it work out for some time before shutting down pagerank completely… with the current start of more semantic analysis by Google, the real contender pages will get in front of high PR pages anyway… of course that doesn't mean link popularity and important links won't be important anymore… just the metrics will change over time…

Found some more posts on this – many more via trackback…
