Return of the Winkelvii

Mark Zuckerberg may have Facebook (and its ever-shakier stock valuation), but the Winklevoss twins have a new social network for professional investors.

From the WSJ: "After finishing their competitive rowing career, Cameron and Tyler Winklevoss launched Winklevoss Capital. The Twins have invested $1 million of their fortune in SumZero, a new social network for the investing community."

They're funding it from the ~$65 million settlement of their legal battle with Zuck and Facebook Inc..

"The band is back together," Tyler Winklevoss told the Wall Street Journal. Be afraid. Be very afraid.
