What is the Best dApp built by the Steem Blockchain?
Excluding Musing I would say:
1: Utopian-io: There is currently no front-end so it doesn't feel like a dApp. But the Utopian v2 platform should be out soon! Utopian is probably the largest and best organised of the dApps, with 3.6m Steem Power, a team of 50+ moderators, a large and open community and lots of developers to help drive it forwards. Open-source is growing in prominence in the world, as evidenced by Microsoft's recent $7.5bn acquisition of Github, and the work that Utopian does for open-source projects could make it really big news outside of Steem as well as inside. Utopian recently welcomed Rocket.Chat and CoinGecko to its VIPO Very Important Projects list and is starting to make the links that can connect Steem to the outside world.
2: Actifit: It's still pretty small but the idea is a good one, the mobile Apps are built, and the community is growing. I like the idea that it fits with a smaller-reward, tipping-style environment. That style of dApp seems much more likely to attract people to Steem in the long-run than the original blogging set-up which requires huge effort for limited reward. There is also plenty of advertising and sponsorship potential since the user demographic is clear and well-defined.
