Twitter makes an out-of-character move

NEW YORK (AP) - So will Twitter users end up needing to know the abbreviation "TLDR?"

More people may soon find out whether "too long, didn't read" might start applying to tweets.

Twitter is considering doubling the current length restriction on comments sent over the site. Instead of the current 140-character limit, Twitter is testing a system that will let users use a 280-character limit.

For now, longer tweets are being used among a small group of test users.

Twitter acknowledges the "emotional attachment" some might have to the 140-character limit. But it said the new limit, while it is double the size of the original, is "still brief."
