We've got 2 excellent talks from a couple of our friends who really know their stuff. (ketovangelist.com)
The second excellent talk was given by Dr. Ashok Gulati from Indian Council for Research on International Economic Relations. (crawfordfund.org)
One bonus I can't resist adding: Jen Simmons's excellent talk on the graphic design possibilities posed by new CSS properties (CSS Grid!) (epubsecrets.com)
