HOT looks like Alibaba in the blockchain world. Every dapp has its own chain and uses DHT to manage data. Because data is decentralized and does not require node synchronization, hot is much faster and much less expensive.
But I don't think users need a neutral twitter in the short term. Data is just a by-product of social networking. What really attracts users is people on social networks. So I think HOT still has a long way to go.
