He can wear what he wants or go dressed like a drug-addled tramp, just as long as he doesn't come off as one. It's not how he looks or what he wears but the the way he acts and the content of his words. If you had no idea what Bitcoin was, you still wouldn't after watching that and the few other videos of him I've seen.
What he said seemed pretty coherent. No, he didn't give a beginners talk on what Bitcoin was, but he did talk about how it can change society and where the problems are.
We each add our individuality to things, and I really like where he is coming from. No, I wouldn't want him to be our spokesperson, but being decentralized, I
would hope we never have one...
Its about sharing
