Google SearchWiki
Another new innovation from Google. They are so far ahead in the search game and every innovation basically accelerates them away from MS and Yahoo even faster. I'd characterise SearchWiki as a blending/blurring of search and bookmarking. They need to unify it with Google Bookmarks, Search History and Notebook which will probably happen over the coming 12 months. The outcome is the going to be a searchable bookmarking and annotation system backed by Google's index of the web so you always find something and often it's the best possible. An amazing display of personalisation at the largest scale.
