[twitterfeed](http://twitterfeed.com/) seems promising, although I haven't tried it yet. It even lets you manage the format of the tweets and supports post filters. ![twitterfeed][1] There are also a few plugins for Wordpress such as [WP to Witter](http://wordpress.org/extend/plugins/wp-to-twitter/) and [WordTwit](http://wordpress.org/extend/plugins/wordtwit/). For Wordpress.com you can use [Publicize](http://en.support.wordpress.com/publicize/) which is included by default. [1]: https://i.sstatic.net/fEKQK.jpg
