In what they're calling the twitpocalypse, it appears there's just too many Tweets out there!



Each message on Twitter is assigned a unique identification number. On Friday evening, the number of tweets exceeded 2,147,483,6471. While that doesn’t seem like a round number, it’s the largest number that can be stored as the data type known as a “signed integer.” Once that number was exceeded, some versions of some Twitter client apps could break in a fashion similar to what was expected during the Y2K “millennium bug” era.
Twitter "twitpocalypse" affects Mac, iPhone apps

Reminds me of Star Trek. The engines cannae take it, Cap'n!!
