"I want to help people make things, and I want to become a better hacker, teacher, and writer. Teaching people to become hackers over email kills all three birds with one stone. :)"

No ulterior motives or schemes, I promise. But now that I think about it, you can add "wanting to talk shop" to the list.

Just checking :) Are you at college or something? How are you finding the time to commit to this projects?

I'm bootstrapping a startup, and plan to find time for this by using it as a break from coding and designing my own stuff. I think if I'm disciplined and efficient I'll be able to find enough time...I hope. ;)
