This afternoon I have installed the Yourls plugin for WordPress. It creates a short URL service (like tinyurl.com or bit.ly) from your own domain, so mine will be http://robparker.org.uk/l/(characters)

The l stands for link by the way! You can see more and even try out the service by visiting robparker.org.uk/l

The plugin takes your posts and publishes them to Twitter immediately, which is frankly the only place they are published too anyway. Its good and I like it, and I hope you enjoy it!
