random fun fact, the creator of Worms used to hang out on a #worms channel on IRCnet. It was a lot of fun for many years, but eventually Andy left and people slowly drifted away as the Amiga scene shrank, and now all that's left is me and a few people who weren't even there in the original era, in a #worms channel on ARCNet (I forget why we moved from IRCnet).
Sadly, I have no logs from the old days, so all I have is memories of lots of CTCP SOUND shenanigans.
yes, i use irssi to hold persistent sessions for all the twitch chats im in. doesn't require anything special beyond an oauth token sent as the server password
You still can, it's very useful for bots and game integrations because you just need an IRC lib in your language of choice. However, the servers aren't IRC anymore, they just have a compat shim that speaks IRC for those purposes.
