It’s been a decade of uploading drunk photos and stalking exes. Ten years ago as a socially bitter Harvard undergrad (if The Social Network has any truth in it), Mark Zuckerberg launched Facebook from his dorm room. Although it still holds a coveted position among Silicon Valley empires and is valued at more than GM and Ford combined, Facebook’s future has some uncertainties. The teen-user population that made it so popular is now waning. For now, the decade-old company can more than hold its own with whipper-snappers like SnapChat.
