Local data, blogs drive Web growth

While growth is slowing at most top Internet sites, it is skyrocketing at sites focused on social networking, blogging, and local information.

The dramatic success of those Internet categories is apparent from a recent online-traffic analysis provided by market research firm ComScore Media Metrix, which examined visitor growth rates among the 50 top websites over the past year.

Top-ranked sites growing the most, ComScore's data showed, 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.

The number of monthly visitors to each site rose at rates ranging from 185 percent (Citysearch) to 528 percent (Blogger.com) between February 2005 and February 2006.
