I just heard about the School of Everything, and can't help but wonder if it eventually could become a good resource for conference organizers looking for educators. According to BoingBoing, this site will be
a new web service that acts as a kind of eBay for people who have something to teach. Potential teachers list their areas of expertise (anything from knitting to programming to driving to yoga to TIG-welding to whatever) and potential students find teachers with a simple search that can be geography bounded (for in-person instruction) or not (for online instruction). It's one of those great, simple, smart ideas that make you want to smack your head and say, "Why didn't I think of that?"
While it's only available to UK users now, Cory says it'll be going global soon. I absolutely adore this idea.
