It's an advertisement you might see someday, if testimony given to the British House of Lords this month is to be believed. In remarks that have stirred up a tempest in the British media and on the Internet, Baroness Susan Greenfield, a neuroscientist at the University of Oxford, warned that the instant feedback and impersonal communication offered by social networking sites could drive human brains and behavior in negative directions.

"As a consequence, the mid-21st Century mind might almost be infantilized, characterized by short attention spans, sensationalism, inability to empathize and a shaky sense of identity," Greenfield said Feb. 12.

So, we might all become blubbering idiots, but at least we'll have friends!
