+
+
+Creating and executing an appealing technical demo to an audience of software
+developers is a ton of work, but there is no better way to get people 
+legitimately interested in your product if you land a great demo. The 
+inherent difficulty involved in exceptional technical demos also creates
+a large moat that prevent others from easily copying the work you put into
+the demo.
+
+The most important parts to a standout technical demo are:
+
+1. show how to solve a difficult technical problem, as easily as possible
+1. take the audience on a story arc
+1. do it live (especially if you include code)
+1. rehearse constantly, both happy path and recovering from errors
+1. speak plainly but accurately
