Excellent talk on a topic that's very relevant but not that common to hear in meetups. The slides could use a bit of "pimping" :) and I'd recommend using less bullet-points, but the important stuff was all there.
I especially enjoyed how you involved the audience and the back and forth that was possible thanks to that.
Was a verry intressting topic, would enot say that this was your fist one ever. Job well done!
