I like the Ethereum concept and there are surely a lot of possibilities with blockchain and turing-complete script language inside transactions.
But what I worry about a bit is the marketing issue. We have seen a lot of promising new technologies emerging in a new altcoins like Mastercoin, NTX, Peercoin, Colored coins, etc. But it seems all of them are struggling to get traction, since they are being out-competed by currencies with a strong grassroots marketing, like Bitcoin or Dogecoin for example.
You can have better technology, it seems, but if you don't have strong marketing and large crowd of enthusiast, it's very hard to succeed. Are there some strategies to tackle this problem?
