Cool, but is anyone using IRC day to day in 2021? Not trying to be snarky, I'd love to, just don't know where I'd be.
Right now I'm working with a dev from libera on a client that aims to replicate a lot of things experience-wise from newer chat services. Hoping that with that, smaller self-contained servers can become more of a norm~ But for now, your best bets for finding activity are probably Libera and a couple of the other larger networks.
