Excellent talk by a great presenter. My only suggestion would be to have a bit more of an introduction - it felt like the talk jumped straight into the "bullet points", and while they were great, I was left wanting more of a "hook" to get me into the material.

A very worthy subject, and well demonstrated by the speaker - he put himself where his mouth was by giving a talk! I appreciated the use of Jazz to illustrate some of the points, but another talk given awhile back suggested that we want as little to detract from the speaker as possible. Focus more on demonstrative content.
