I was considering adding IRC but I thought that almost no one uses it these days (sadly!)

Ideally yes, I'd like to implement it. It's a stable protocol that's not going to change, so there's not much cost in maintaining it.

What are you using IRC for?

There already exist tons of high quality irc clients, so there's no reason for irc support to be high priority. I see eul's reason to exist to be more to alleviate the weight of having several low quality messaging apps open at the same time.

You are right. On the other hand it would be nice to have all protocols supported in one app, so one day IRC support will definitely be there.

IRC is still very active in certain circles, though relatively few these days. Many open source projects have channels for discussion and support for example.

#blender and related, the freenode community is still very active for real time support for many projects. I think IRC still could have a great place in the world - decentralised, open, etc. The ui is just very expectant that you already know and understand the ecosystem.

Needing to know user /auth stuff happens by sending private messages to bots, and other insane hacks.

Not OP but I use IRC daily in channels like #nodejs and #elixir to get help and help others.

I use irc pls add
