Hot Potato Team Could Be Headed to Work on Facebook's News Feed, Or Location Service, Or Questions?

Out of the last five startups that Facebook has bought, four of them have had something to do with sharing information in a social news feed interface or sharing location data, if not both. All of the sale prices have been relatively low, too, with the acquisitions largely intended to bring in talented developers. So it makes sense that Facebook may be buying Hot Potato, a startup that lets you create and share a stream of information about events, and anything else.
