Web 2.0 Etymology
I've never used, or even felt anything approaching ZOMG until I heard that Facebook was launching a chat program. According to Wiktionary, ZOMG is an "overzealous typo of OMG, resulting from the proximity of z to the shift key." That sort of reminds me of the Facebook group, "I Prematurely Release The Shift Key!!1", whose members are "interested in earning big $$4."
