TweetDeck in #280Characters

Twitter has released 280-character tweeting, but only to a small group of people during a trial period. This Chrome extension ~~adds~~ once added the ability for everyone to tweet in 280 characters on TweetDeck and Twitter.com.

~~Install the extension on the Chrome Web Store.~~

The source code is available here on GitHub and pull requests are invited.

This extension works thanks to tricks by @Zemnmez and @Prof9. It's likely Twitter will modify their systems to prevent these hacks, so don't be surprised if it stops working.

Update Sep 28: The party is over at twitter.com, which now appears to be validating tweet length at the server, so this extension no longer enables 280-character tweets there. But it still works at tweetdeck.twitter.com! 🎉

Update Oct 5: This extension no longer works. Twitter and TweetDeck are now both validating tweet length at the API. ⚰️
