I really agree with your first point. There is an incredible amount of potential in web pages as teaching tools. I'd love to see someone make a math notebook environment for tablets with a stylus. It could pull up a sort of intellisense as you write (for example first, second, nth derivatives, common expressions, suggestions for factoring, etc.). It could have graphs. It could have a reddit like QA section. Really, there are so many unexplored ways of connecting people who are struggling with a concept with just the information they need. Who wants to watch a ten minute video to hear about that one equation three quarters of the way through? Just learn what helps people like them and offer it up as potential solutions while they are working through problems. There is the possibility of pre-endering Mathjax but that seems like it would be a lot of work.
