BACK TO SCHOOL: Sometimes we daydream and take a stroll down memory lane to relive those fond memories of college days. Facebook does too, apparently, returning to its origins with Groups for Schools, campus-specific networks for affiliated students and faculty (restricted to active .edu addresses). Users get to share notes, updates on club meetings and events, and upload files up to 25MB. ZDNet has more deets here. GOOD surmises that this move may be a response to Google+ and its promised foray into schools. Doesn't hurt either that Facebook has an impending IPO going for it.
