Memo to Badoo, Bebo, Catster, Dogster, Facebook, Faceparty, Flickr, Flixster, Hi5, Hyves, Imbee, Imeem, MySpace, Mixi, Pizco, Pownce, Takkle, Twitter, Virb, Vox, Xanga, Xing, Zoomr ... and the 3,245,687 other social networks clamoring for our limited attention spans: We got it. Making connections between friends is cool. Sharing photos and videos, even cooler. But it's all so... 2006. Haven't you got anything new to show us?
Here's a safe bet: Two years from now, 90 percent of these networks will be gone and their founders will be back working at Starbucks. I'll have a double mocha frappucino, please.
