Add Gopher to the stack too.
Gopher: Curated blog, sites, services and even news aggregators. No bloat, no JS, no waste. No ads. No clickbaits. Pure raw text.
gopher://magical.fish, gopher://1436.ninja and gopher://sdf.org as my main source/portalish gopher holes.
IRC: tech channels, sometimes news. Libera.chat it's my
main network. No bloat, too, you don't need an i3/Core2Duo
to talk to someone.
Usenet: techgroups, delayed help available. No need to be online 24/7. You can pull posts once a week and everything will be fine.
If you are a geek/nerd, you can code your own client on most programming languages in just two weeks. With something like TCL, Perl, Python or Ruby, a single week would be fine.
The opposite is different. An IRC server requires maintenance, and INN can be crazy difficult for Usenet, but
for Gopher it's dumb simple to set up both content and a server. And, yet, there are pubnixes and tildes oferring this even from SSH, for internal and federated use against other pubnixes. And it's amazing.
