The problem is that people only get paid to teach what some bureaucracy deems important, and people are only rewarded for learning those same things in a traditional educational system. Anyone should be able to offer to teach anything and even make some cash at it if enough people wish to learn it. It would be oversimplification to say I want to create an educational website, or a tutoring website, or an academic wiki, or a how-to wiki, or an interactive knowledge sharing community, or an open forum for generation and consumption of comprehensive lesson plans. There are a lot of oversimplifications I could make. That's why I have umpteen pages of notes accompanied by a full business plan to get the idea more concrete.
I think I've divulged too much for a public post. After all that though, if you're still interested, I'd be happy to share further details more privately.
I live in South OC at the moment...
