Boardtracker is a device I've been using for awhile now. Instead of visiting all my favourite boards every day, I now get alerted to keywords and subjects contained in threads on any board, right on my ICQ. It's a very handy device.
Plus, right now they're having a contest and giving away some cool prizes. A 19" TFT monitor, HP/Compaq iPaq 5450, Sony powershot DSC-V1 5MPixel, and one of those cool new Apple iPod 30GB MP3 players.
