The trick is in getting it to the masses in a way that is easy for them. Right now you're still at a stage where to get tokens you send Ethereum to a long string of numbers and you get a thing that tells you that you got x number of tokens. It's all still very "out there."
An improved user interface (UI) could be extremely helpful in getting adoption. Otherwise, even if you have a token, people might not buy. It's more familiar to send a check.
