But much more than just size has changed. At a certain 'tipping point,' social media begin to function in ways that, when they were smaller, would have been impossible. Facebook and Twitter have been credited as playing roles in the "Arab Spring" in the Middle East, particularly in Egypt and Tunisia; Facebook's founder has been the subject of a major Hollywood film; and twitter feeds and cell-phone photos has brought down politicians of every party, sometimes within a matter of mere hours. It certainly sounds as though these technologies have crossed some threshold, altering the fabric of reality itself -- but then, of course, one can look back at similar claims made about virtual-reality video helmets (anyone remember Lawnmower Man?) and wonder whether these revolutions will seem such a few years from now.
Three key developments have shaped this period: 1) Social media with "presence" -- a main page at which users can add or copy content, offer images, texts, or video of their own making or choosing; 2) Sites with instant linkability -- the ability of users to add (or subtract) active and immediate connections to other users; and 3) Sites that bundle essential tools (e-mail, instant messaging, and other software capabilities. Finally, all of the above, or at least the survivors in this highly competitive field, have gone multi-platform; no social medium of the future will thrive unless it is available on desktops, laptops, tablets, and smartphones, and has some system of synchronizing all its users' preferences and updates.
So what next? The spaghetti is still being hurled at the (virtual) refrigerator wall; Blippy, a site that enabled shoppers to instantly "share" posts about their purchases was hacked, and credit cards compromised -- so much for that! -- Google tried to launch its own "Wikipedia killer," dubbed Knol, but the site filled up with spam so quickly that it became almost useless, and Google discontinued it; it also failed to generate "Buzz," a hot-button social networking site that offended many users with its auto-generated list of "contacts," and Apple stumbled with Ping! an addition to its popular iTunes platform meant to enable people to share news about music purchases and performances. The latest entry Pinterest, allows users to "pin" content to one another, with a focus on bargain shopping, and has the unusual distinction that a majority of its users, in many surveys, are women. But will it go the way of the Lifetime network?
It may seem we're already "shared" too much in this era of TMI, and these social media may be reaching their limits -- but I wouldn't bet on it.
