So what are these networks and what can they do for me?
Indianapolis Star -- LinkedIn was actually one of the first niche social networks on the
Web. It was founded in 2003, got off to a slow start, but is now the
seventh-largest social network on the Web, according to
Nielsen/NetRatings. It grew more than 160 percent from August 2006 to
August 2007 -- faster even than Facebook.
Niche in Growth: Big Social networks see Web traffic declines
Minnesota Daily -- Research released from Internet research firm ComScore Jan. 23
confirmed that the top two social networks, Facebook and MySpace, both
saw their traffic decline by double-digit percents.[One] possible reason for the reduction of customers to these sites
is an increase in niche networking sites ... for example, for
people who like to travel. While Facebook has applications for
travelers, it's not the same as a site devoted to these people.
Generation MySpace Is Getting Fed Up
Business Week -- The MySpace generation may be getting annoyed with ads and a bit bored
with profile pages. The average amount of time each user spends on
social networking sites has fallen by 14% over the last four months,
according to market researcher ComScore. MySpace, the largest social
network, has slipped from a peak of 72 million users in October to 68.9
million in December, ComScore says.
