I totally agree that Splinterlands was the one app that did many things correctly. They were earning money with people coming to the game. So they attracted more people from outside and it allowed them to earn money, the game to grow and also to hive to grow. If you build an app and you can earn money with it, you will do everything possible to attract as many people to it as possible. With DHF funding, apps on hive don't really have much incentive to bring in new users.
