URL shorteners are something that was a hot topic last week, with the almost shutting down of tr.im and what not, as well as the launching of vb.ly. Inspired by this good work, as well as a few rants on the subject I decided to go ahead and launch my own shortener xmtr.us using the same yourls script that powers vb.ly. I have to say, it was really really easy to set up and it works great. I highly recommend Yourls it to anyone that has need or want of a URL shortener, and would like a little more control than can be provided by a third party.
I did have a little trouble with the WordPress plugin, which auto-generates short urls for each post, and can then link up to your twitter account. It just didn't work for me out of the box, but today there was an update to the plugin that fixed it, and now all works as promised. Sweet!
