I'd join - not joking either! I'm willing to bet that most technically-minded people have devices that act strangely, and yet are powerless to fix them due to, say, the difficulty of getting GDB to connect via the non-existent serial port to capture the stack trace of a once-a-week glitch. I'm in that category with a few of my devices right now, so a group where people could explain device drivers to each other would be really interesting to me.
