Those loquacious few who use Twitter must have run across the predicament of hitting the tweet max character limit and still have more to write. For them, there’s a little utility called Longtweet.
It allows you to write as much as you wish and post a shortened message with a link to the full text on Twitter. Unlike Tall Tweets, TwitLonger, and RichTweets, there is no need to give Longtweet access to your twitter account. It’s safe!
