A study by ComScore Media Metrix showed that blogs and social sites have a much bigger growth than more established sites like Google.com or AOL.com, reports Washington Post. "Top-ranked sites growing the most were Blogger.com, a personal publishing site; MySpace.com, where young people do virtual preening and share musical tastes; Wikipedia, an open reference site jointly edited by millions of people; and Citysearch, a network of local guides focused on cities. Google Inc., for instance, bought Blogger.com in 2003; the number of people posting or reading material at that site jumped to 15.6 million last month from 2.5 million a year ago."
Google has a much bigger growth than rivals Yahoo and MSN, although Yahoo has invested more in community features, in social networks (Flickr, del.icio.us, My Web 2.0) and still dominates webmail market.
