Twitter uses t.co short URLs in all tweets. All links will be forcedly converted into t.co domain which is ugly, troublesome and blocked in my hometown China (Damned).
This plugin will help you get rid of t.co.
It is based on Twitter Tools. When a post is created automatically from a tweet, this plugin will unshorten all t.co short URLs in the tweet.
