Google 2.0: Google Universal Search
Danny Sullivan writes: “Google is undertaking the most radical change to its search results ever, introducing a “Universal Search” system that will blend listings from its news, video, images, local and book search engines among those it gathers from crawling web pages.”This basically means that you will see a mix of different types of results, for many more if not all searches on Google.
PS. It’s not quite clear wether it’s Google 2.0 or 3.0: other people and see comments on Danny’s blog think it’s Google 3.0.
