@Placholdr It'd be similar to leaving Twitter for the Fediverse. IRC and XMPP have the advantage that the protocol's open, so you can use whatever client you prefer, and XMPP is also federated (originally IRC was too, but today it's fragmented) so you can join whatever instance you prefer.

They also have similar downsides. It's a communication tool, so there's little utility in it if the people with whom you want to communicate refuse to switch from Twitter/Discord. You'll also find more bugs in the software than you would with the proprietary alternative, unfortunately.
