Upon leaving the TED alternative BIL Unconference, Rahmin Sarabi wanted to see what his friends had to teach each other in a similar co-education framework. The community-powered learning community (un)classes became Sarabi and partner Jonathan Strauss' chance to see what smart folks would be willing to share, and the result is a good “what to do on a free Saturday afternoon” solution given the classes' informal nature and wide range of content. Peer instructors have raised their hands everywhere from New York to Boise, and the Cloudspace-powered community offers everything from the very practical  (Accounting for Dummies and Salesforce) to the fantastic (cheesemaking and straight razor shaving). Talk about the joy of learning.
