At one point I had a request from someone to add the capability to generate at a random link to one of the many fine sites tracked by UUpdates. So I figured.. why not? The original version pulled out a full list and let the client pick a site at random. This has some benefits for caching, keep a copy, but is generally inefficient. This new version just gives you a link and corresponding title of the randomly select site.
For fun, there is also a page that will show random site details.
