OurDoings is it. I still use the "wishful thinking" programming methodology I learned from SICP. I'm married with 3 kids and a separate day job, and don't think I could have pulled this off using a less programmable programming language.
That's cool. Could I interview you about developing web apps using Scheme? I'm working on a blog post / interview on the topic w/ all the people I know who do Scheme web development.
Anyway if you are interested I'd love to hear from you, my email is: idoh@idoh.com
