It's just a question of what the 'killer app' will be. Splinterlands already has loads of users, but most do nothing elsewhere on Hive. I think we need to find a niche where Hive can make a big difference. Some will say that could be the people who get banned from other platforms, but they may not attract the masses. Just have to keep pushing in lots of directions to reach that critical mass.
