[At South by Southwest Interactive] once the badge-decorated horde spilled into the halls or went to the hundreds of parties that mark the ritual, almost everyone walked or talked with one eye, or both, on a little screen. We were adjacent but essentially alone, texting and talking our way through what should have been a great chance to engage flesh-and-blood human beings. The wait in line for panels, badges or food became one more chance to check in digitally instead of an opportunity to meet someone you didn’t know.
