> While some people might use XDCC, it seems more common to post a filehost link, similar to sharing pictures. You can also exchange magic wormhole codes, link a torrent file, give ipfs info, share a server where you can use sftp, etc. I personally don't like XDCC and never touch it.
What you're saying is that IRC file sharing is so bad that people use anything other than IRC file sharing.
> I run irssi (tui client) inside of tmux on a remote server (in the house of someone I know, within 20 minutes driving distance).
A unix shell account on a managed server would cost at least $5/month at commercial rates. Most people aren't willing to pay that much just for online chat. You don't like IRC, you like the massive favour this person is doing you.
> I ssh in and attach to the tmux session from my main PC and my phone, getting the same full client and experience from both, allowing me to do powerful things like use irssi aliases, shell commands, and tmux shortcuts even from my phone. Much more powerful than a dedicated mobile client.
It's not though. A native, customizable chat program will let you do everything you could do over ssh, but also do things that take advantage of your device's unique capabilities like touch gestures on phone.
> Plus I can run mail and torrent clients in another tab, quickly look at IRC log files going back years in another pane, etc.
Again this is an example of the best thing about IRC being not IRC.
