• Twitter is testing out 280-character limit tweets, doubling the standard 140-character length.

• The company saw the shorter limit was " a major cause of frustration for people Tweeting in English."

• Japanese, Chinese, and Korean characters will not get the extension because it is easier to say more in smaller amount of characters. Twitter is experimenting with doubling the length of a tweet from 140 characters to 280 characters.

The company wrote in a blog post on Tuesday it was rolling out 280-character limit tweets to "a small group" of users who tweet in languages that may have had issues with trying to fit everything they want to say.

"We understand since many of you have been Tweeting for years, there may be an emotional attachment to 140 characters – we felt it, too," Twitter product manager Aliza Rosen wrote. "But we tried this, saw the power of what it will do, and fell in love with this new, still brief, constraint."
