1. People who consider themselves the literati of the digital age.
2. Arty geeks, as distinct from technorati or tech-head geeks like script kiddies.
Singular form: digiterat. Cf. technorat.
Joe's one of the technorati - he dreams about scripts to bulk change Unix permissions. But the digiterati are people like Mary. She's so cool she uses her iPhone to photograph a politician giving a speech, downloads and runs an app to morph it into a damaging caricature, and uploads it to Wikileaks before he's finished talking - all while tweeting about it and drinking a chai latte.
