I just put together a page that prototypes what I'd like my tutorial pages to look like eventually: rbwhitaker.wikidot.com/test.
I'd love to hear from people about what you think. Send me an email, or send me a tweet, or leave a comment here, below. If you like it, great. If you think it's terrible, that's OK too. I'm not committed to it at this point, so feel free to express your opinion in any way that you like!
