Being a hacker-type, I did everything with it.
Email? Forget waiting for some bloated email client, I'm using pine.
Want some html on my personal page? Use vi.
I think they didn't take away my access for years after college, and I would sometimes login and poke around just for fun.
I do blame them, along with the rise of Java and the awful gui toolkit motif for convincing me to drop out of computer science and switch to Computational Math for my bachelors degree. I was so frustrated that our grades were dependent on learning something that I saw as completely worthless in light of the dotcom boom happening at the time. I wanted them to teach us web technologies, or at least some good system code, but all I got was broken x11 and awful performance.
