Love your optimism and I mirror the sentiment. The whole idea of being a "Steemit killer" already points at the fact that they're doing something right. I run into people who whine about the reward system and I remember one person I met on Publish0x while shilling Steem there crying about Pioneerism or something like that, all that and more may indeed be problems in this dynamic system but I reckon we've made plenty progress in a short space of time.
Either way, there are a shit ton of people available in the world and one hundred million people around here will be a big win.
