I was just discussing this with a buddy today. He was asking about dapps and everything I could list has no mobile interface at all, that I know of. No one is going to Murmer instead of Tweet as long as you have to do it through a browser and those are the kinds of dapps that need we need out there the most. They span the masses. Games are fine but crypto games are a demographic within a demographic and not really a big enough target to draw the numbers we want to get to.
Mobile development should be a top priority.
