Google is dumb

Mary Ellen Bates article in econtent magazine summarizes nicely one of the short comings of Google, Google Scholar. It does not offer "clustering of search results, which helps conceptually narrow your search" IMO Yahoo also has the same problems when presenting search results. btw with their new yahoo mail search and dynamic clustering they might be in the right direction.
Glad to see that someone else in the industry is calling Google's results "dumb".
