I used to love having a job where I had regular interaction with customers. It really made a difference in my ability to improve the features we had, and to design new systems which would be more likely to succeed. I miss that, and I wish more companies found a way to put engineers in contact with actual users...

...but if you tried to make me do even one sales call, at all, ever, for any reason, that would instantly terminate my interest in working for you.
