In the altcoin forum i saw a question about the best social media platforms to promote an ICO.

Someone stated you can either target a smaller informed audience in more "scene" specific platforms like this forum, or you can try to reach the public on facebook or youtube.

But how can you spread awareness and enthusiasm for cryptocurrencies in general, thus increasing the size of the informed audience?

What are governements and private orgs doing to spread the word or even preventing it from beeing spread?
