This is one of my current works-in-progress.
It was running a really nice car-related theme, but I started getting weird pop-ups, so I've had to revert to twenty-ten for now (customised a bit)..
It's using an rss aggregator, and outputs to RSS, Twitter, and e-mail updates.

I've already been told off for hammering their mysql server, and even got banned for 12 hours, as their DDOS attack detection system thought I was an attacker!
