Some of my coworkers were talking about using RSS to read blogs, which made some of the younger folks in our team ask what it is and why we keep using it.
Some still use iPods to avoid subscriptions and streaming services, my favorite was one of our sysadmins who showed me Gopher.
I’m curious about others though, thanks!
It may have changed more recently (or depend upon country as well), but I was still getting results from old serial/null modem devices about 10 years ago (I worked on the centralized IT side so I didn’t see these devices, but this is what the on-site tech was telling me when troubleshooting things)
