For anyone else out there who has code or services integrated with Twitter, you should take a look at this soon.
The Twitpocalypse is similar to the Y2K bug. Very soon the unique identifier associated to each tweet will exceed 2,147,483,6471. For some of your favorite third-party Twitter services not designed to handle such a case, the sequence will suddenly turn into negative numbers. At this point, they are very likely to malfunction or crash.
Time to haul out some BigInt action.
