So Twitpocalypse has passed and nothing bad happened. No fail whale, dead birds, or broken clients. Now it appears that it was all a viral marketing ploy.
Martin Dufort, CEO of Canadian application developer Wherecloud, says he put up the fear-mongering Twitpocalypse.com page as "a viral marketing move." The page tongue-in-cheekily predicts that when the absolute number of Tweets hits 2,147,483,647 (the highest number a 32-bit signed integer variable can store), Twitter applications using the faulty variable type will be "very likely to malfunction or crash."
This looks amazing.
