It seems Google guys are too busy with the IPO and AdSense, AdWords and new features, and have no time to dance.
I noticed the last Google dance as in June 07, 2004 for my site. I know it from the obvious PageRank difference between the two adjustant entries. The difference is still there. This means, Google didn’t dance since June 07, 2004. 108 passed and there is no change in anything in PageRank.
Cemper also noticed this. Are Google guys too busy with IPO?
