UX. A lot of the applications are similar to what Steem always was, what they need to do is find what people love and make the tokenization a native part of the experience, not a focus or an afterthought. This is a learning process though, and in time and as more developers get involved, innovation and wide use case will be added. If one doesn't like the experience of Steem, they are only here for the money - that'll never drive long-term adoption.
