I love this idea! We need marketing and people who can get the word out. Representation at blockchain events would be HUGE! I'd be interested in doing it as well. Although I don't have much public speaking experience outside of university and the occasional blabbering on YouTube. But, I think I'd be good at it. I know a ton about the industry and the Steem ecosystem as well and I know I could put together a good presentation/pitch deck. I have no problem speaking in front of large numbers of people either and have done it several times in my life.
Regardless, we do need people to do this and I absolutely support this idea 110%! Good thinking!
