Are Younger Users Cooling to Social Networking?

U.K. communications regulator Ofcom says the percentage of 15- to 24-year-olds with a profile on a social networking site has dropped for the first time, from 55 percent at the start of last year to 50 percent this year.

Some have suggested this means younger users are abandoning sites such as Facebook that no longer are attractive now that their parents use the sites as well.

The other explanation is that users are starting to settle in at fewer sites, says comScore.

Younger users are increasingly moving towards Facebook as their primary social networking destination, and using other sites less.
