This is a guide to using IRC for Mastodon (feel free to follow me there!). Apparently, you can also interact with Twitter using an IRC client (it’s all using Bitlbee).
It reminded me that you used to be able to use an IRC client for Slack. Slack removed that feature, although it seems there are still workarounds.
So yeah. IRC is versatile.
