@bender IRC is so simple and lightweight it can run ANYWHERE and consumes so little resources. And it's intrinsically decentralized and in the hands of its users. Of course, it has many downsides, like no history, no concept of "logging in", it virtually does not exist unless you're present... The learning curve / paradigm shift can be quite steep, it is really really niche. But are those things really downsides? Debatable.
