Given the fact that Google doesnt have a formidable equivalent tool for delicious (atleast publicly), I am inclined to believe that many Googlers must have been using delicious for tagging. Now that Yahoo! has bought the company, isnt it easy for yahoo! to keep a tab on the worlds and trajectories of these googlers? Isnt this a bigger issue for Web 2.0 in general, where players have the potential ability to lock up peoples data? Its easier to Do Evil once things fall into corporate hands (as corporations have lower moral and ethical standards. Yeah, thats one thing where sum is always less than the constiuents).
Anyways, Google is falling behind in this MyWeb area and thats one thing that sometimes makes me think of using the yahoo! toolbar.
