Friendster: Slip-sliding away?

Is Friendster traffic really declining, or is it a momentary glitch?
A friend shared Friendster stats from Alexa showing a traffic decline; I plugged them in next to Alexa’s Orkut stats–the picture speaks for itself–that little red line is climbing straight up.

A friend of mine said yesterday, “This whole social networking thing is just like going to a bar…First, everyone runs to one bar, then, the same people run over to the next bar..If you look, it’s all the same people going from site to site.”
While that’s not true of Friendster, which took off with a wide range of constituencies in a major way, it is true in general–so whether Friendster remains popular will tell observers a good bit about the sustainability of the social network space.
