Ask HN: Review my (revised) startup idea.

About eight days ago, I asked for advice about starting an on-line college that offers small classes and teaches using the tutorial method. (1) After talking with friends and family, and thinking about pewpewlasergun's advice, I've decided to do is create a service that offers a full range of courses on technology.

Some example courses: * Introduction to Mac OSX * Introduction to Linux * Programming (Python/Ruby/Clojure/etc.) * Web development (HTML/CSS/JavaScript/Rails/SEO/etc.) * Bookkeeping (Quickbooks/Peachtree/etc.) * Computer Science (I think it's sad that so few universities teach algorithms and data structures anymore.) * Introduction to social networks * And more.

I'm considering using Skype an the virtual classroom because it's cross-platform, and free.

All thoughts, ideas, and suggestions are appreciated. Thank you.
