Sometimes I think there's already too many bullshitters in this space. LOL, but you make a great point. Most of the alt-coins seem to leave that aspect up to their individual community. That is one thing the dogecoin community really has going in it's favor. The community even sponsored a NASCAR driver. That's huge ! Most of their support came from community.
I think as cryptocurrency grows though, dev teams will see a need for marketing directors and PR folks to promote their coins. As competition grows so will marketing strategies. Marketing folk or professional bullshitters as you call them :) will probably be just as important as good developers in the future.
That is what I am betting on. Marketers are just as important as the devs once mass adoptions shows up.
