I don't think you are meaning quite the same "early internet" if you are referring to Slack channels xD

Pretty sure they were addressing the "non-usuable" part and not the "early " part.

As sibling comments have correctly guessed, I was only responding to the "non-usable" part of the parent comment. But yeah, replace slack with IRC, email, or whatever you were using at work back in the day.
