After using ed and other Unix programs I convinced a member of the
UCSD Pascal project that having a line oriented editor would make sense.
YALOE (Yet Another Line Oriented Editor) was the result. It took almost all
of the commands that ed did and so familiarity with one would allow you to
work with the other.
The simplicity of ed was so nice. One other thing using ed forced me to do
was to keep my files small. Large files would quickly become something you
had to hunt around in. Small files were easier to edit.

I first started using emacs. I have also grown to
appreciate ed, though I
learned that quite a bit later.
If you were on some 300 baud dial up modem, ed made tons of sense. You
had a mental picture of the file in your head, you didn't need to see
all of it in real time, that was wasteful. ed let you see as much as
you needed and as little as was productive. And it worked without
termcap. ed rocks, it's yet another little program that does what
it needs to do and no more.
ed was like a lot of stuff that Bell Labs did that dated back to the
days when getting a print out took a day or so. pic(1) is a great
example of that. I *love* pic because I can look at the input to
pic and I can see what it will look like. xfig and friends are
not so much.
