Mary-Jo Foley published a news story that Microsoft started a public test of a new Twitter-like notification service called Vine

The Vine service initially was developed by the Windows Live team, post Hurricane Katrina. I heard a bit about the service back in June 2008, after which the service — like a number of Windows Live properties — seemed to just disappear. It turns out the concept was passed over to Chief Research and Strategy Officer Craig Mundie’s division and incubated like other technologies in Microsoft’s Start Up Business Accelerator group. “Eventually, products and services started in the accelerator will transition into one of Microsoft’s existing business divisions,” a spokesperson said.
