Free! NO EXCUSE LIST: As the name suggests, this site aggregates "the best places on the web to learn anything for free." Topics include Academics, Cooking, Music, DIY, Languages, Programming, and Music. We don't claim to be experts in any of these topics, but as far as Academics and Programming go, these guys are on the ball (technically TED-Ed is missing but they included TEDTalks). If you find any important resources missing, be sure to shoot a note to email@example.com.
