Optimizely is a superb example of the democratization of software development. You don't need an engineering degree to fire up Optimizely and start testing how design changes on your website -- down to the pixel level -- affect things like time on site, closing sales, navigation, etc. The a/b testing Optimizely offers is just one example of a new wave of tools born of the internet, and designed for how people work, shop, research and entertain themselves online. Andreessen Horowitz's Scott Weiss, who is taking a seat on the Optimizely board following a16z's recent investment, a16z Partner Tom Rikert, and Optimizely co-founder Dan Siroker discuss the next wave of internet tools, where entrepreneurs are headed next, and how virtually anyone can avail themselves of this technical brawn.
