Was reading old discussions about why did Slack win out over IRC (for some definition of win?)
https://tedium.co/2017/10/17/irc-vs-slack-chat-history/
Found these quotes interesting.
"Why is it, out of all the prominent internet protocols in use during the early ’90s, only two of them—email and the World Wide Web—have managed to hold on in a way where most people use them on a regular basis" -- Ernie Smith 2017
"Why did slack win?
Because whenever somebody asked for:
* 24/7 presence, the reply was "you can do that with a bouncer"
* backlog, the reply was "you can do that with a bouncer"
* full text search, the reply was "that's up to the client implementation"
* file sharing, the reply was "it's already possible with XDCC"
and so on and so forth.
Basically, it's not that Slack is great, it's because IRC as a whole just refused to adapt to what users actually wanted/needed." -- em6m 2020
Not saying I agree exactly, just interesting.
