Just quick post to alert anyone who uses Twitter, and who might care if it stopped working, that they have run into a problem similar to the Y2K bug of nearly a decade ago;

Like any database, every tweet has a number that uniquely identifies it in the stream, and that number is about to reach the limit for a signed integer, which the word is that most twitter software would be using to store the number;

So if twitter is down around june 12-13, thats probably why, and if you use twitter software (such as twitterific on the iPhone), you may need to get an updated version.

UPDATE: Around 11:30AM local time, this in from the twitterific folks;

Twitterrific 2.0.1 for the iPhone is indeed experiencing problems with the Twitpocalypse. Investigating now, we apologize for the problems.
