I recently had the opportunity to take an online public speaking class from a local company here in Austin, Thinkwell.
I'd never participated in any formal online education before (except for defensive driving, which was much less pleasant.) It is a great resource for people who are home schooling their children too.
Increasingly people are getting degrees online, software product training online, and other kinds of education too. There's plenty of competition in this field but Thinkwell's online education system seems to really be one of the most professionally put together examples out there.
