Bitcoin is like catnip for computer nerds.

I looked into mining, decided not to compete against people who don't amortize their hardware.  I finally got some funds into Mt Gox, and I've been trading the last day or so.  I'm placing orders manually, and using the Bitcoin Exchange Watcher program to alert me on executions.  I'm actually a bit ahead of the game, having made more trading that I lost from the general decline. 

Meanwhile, I experiment with the Mt Gox API, with the idea of writing a bot to trade for me.
