Not sure, if I miss that. I read about hacker culture and such, but my own limited experience of the early nineties of the labs of a large university weren't all that romantic.
I recall that some more experienced users poked fun at newbies (who didn't know of xauth) by making their workstation bloke like a sheep. While that was fun, there was no other interaction, quiet, anonymous and uninviting like a library reading room.
Once me and a team mate shared a whole lab with only one third guy. My mate had a cold which he neglected and during the session passed out, hitting his head hard on the desk. I had to shout at the third guy to solicit his help. He seemed to be content hacking on his terminal and let my mate die as long as he'd be quiet about it.
In the same lab (might have been the same session earlier, I don't recall) one fellow not being member of my team ran `crashme` on the shared server (pre-Solaris SunOS, iirc). He apologized with the words (paraphrasing) "I didn't expect it would actually crash" when the server in fact did. We were not amused.
Mid nineties the labs got deserted as most everyone was working from home.
