Recent data from Experian Hitwise on social networking sites confirm what most of us already suspected: Facebook’s growth shows no sign of letting up, Twitter is becoming increasingly popular and MySpace continues its dizzying descent.
Facebook accounted for 58.6 percent of all U.S. visits in September among a custom category of 155 social networking Web sites, Hitwise reported.
That’s truly amazing: Facebook now has nearly 60 percent of the social networking traffic in the U.S., up from 19.9 percent in September 2008.
And while MySpace is No. 2 with 30.3 percent of all U.S. social networking site visits, that’s down from 66.9 percent a year ago.
Even in a category in which it leads other socnet sites — average time spent on site — MySpace can take scant solace. Its 25.6 minutes per visit is down 12 percent from last year and is barely ahead of Tagged (25.2 minutes, up 8 percent) and Facebook (23 minutes, up 23 percent).
Twitter was at No. 4 for social networking site visits, with 1.8 percent of September’s share. A small percentage, but a 1,170 percent increase over last September’s 0.15 percent.
