Twitter has a 140 characters limit when making tweets and if you’re wondering how to make tweets longer than 140 characters in twitter, then Twitlonger is for you.
Twitlonger is a service which lets you post to Twitter when 140 characters aren’t just enough. It is like twitpic for text, where you can write tweets which are shrinked and posted to your Twitter stream with a link to full conversation. The service uses OAuth to login, making it completely secure.
