It was the language we used for assignments in my 2A Computer Science course ("really just an introduction to Unix"). There was only one computer with an Ada compiler on it, a 68k-based SUN server shared among about 100 students.
The compiler was... not fast. And with 100 users, many of whom ^Z'd instead of ^C'ing, things were less good.
Long story short, this was how I learned vi, the power of NFS, and USENET.
