slack-term VS quotable

You can still find terminal interfaces for a lot of these things, including Slack: https://github.com/jpbruinsslot/slack-term. I don't use Emacs but I imagine you could integrate that somehow if you wanted to.

If I accepted having an intermediate jump box, then things go even farther down. Any with a telnet client works, and with something like ZiModem that opens up literally anything with a serial port. I've done "real" work from an Atari 8-bit and Commodore 64 by telnetting to a jumpbox and then sshing into my work Macbook. Spending a whole day that way would be pretty challenging but it could be done. Throw in slack-term and I was able to even keep up with company chat. I was only doing it for fun so I didn't go all the way but I could have set up our g-suite in a terminal IMAP client.

Slack/Discord This is the biggest gap for me so far. I haven't figured out how to get slack or discord to load in firefox. Those sites just redirect me to a page that tells me to download the Android app, even if I spoof the user agent. I use Slack for work, and Discord for communicating with some friends and family, so I'd still like to figure this out. The closest I've found for slack is slack-term which is terminal-based and seems to be abandoned. But it actually works (not well, but you can read and write messages), though the user experience is truly terrible on the phone, since you have to use the on-screen keyboard to do anything. Supposedly there is a matrix bridge, but I haven't tried it yet.

NB. On integrating slack & other webby things. Terminal applications might be a big help here (the Windows terminal now has excellent compatibility if you’re using Windows). For instance, there’s a slack plugin for weechat (a terminal IRC / chat client) which by all accounts works pretty well. Or there’s this client that runs directly in a terminal.
