I love Dave. Seriously, I absolutely love this man.  Why, you may ask?  Because he is one of the funniest, brightest, sarcastic, dry-witted, and pleasant people I know.  Probably most important, Dave is able to hold my attention when he presents on topics as complicated as distributed ledgers by explaining the impact of sensors and distributed ledgers with respect to one's undergarments.  Seriously, he's done that. Oh yeah, Dave's also the Director of Innovation for Consultant Hyperion.
