A few months ago someone posted a 247 character tweet, way larger than the usual 140 limit. Amer from ThoughtPick worked out how they did this and decided to break the record with his own 250 character tweet.

Amer spoke of two ways to achieve this:

Method 1: Load twitter.com. Disable Javascript, reload the page. You’ll notice that the character counter disappears. That’s it!
Method 2: A more geekier approach using Linux command line: curl -u username:pass -d “status=your long tweet…” http://twitter.com/statuses/update.xml

I’m a bit surprised that Twitters 140 character limit can be broken so easily. I wouldn’t be surprised if they fixed this in the future so if you want to write a very long Twitter message, now’s the time!
