It's been a bit slow around here. Google has given no indication of interest in the uprising they have created amongst their devoted user community.
However, just today, Yahoo! announced the introduction (currently in limited Beta testing) an online "Search Pad", which appears to mimic some of the Notebook functionality.
Once again, I find it interesting that Google is stepping away from a valuable product while Microsoft and Yahoo! are moving towards incorporating similar functionality. This functionality is a part of the future of web browsing.
