We don't, we call our users "users". They are the product we are selling to our customers. We call our customers "customers". Why is he taking such a stupid question as a call to change the way he thinks instead of just answering it?
>No one wants to be thought of as a “user”
Excuse me? I am perfectly content with being thought of as a user of site X when I am a user of site X. I am not a customer of google's, I am a user of their search engine. I am not a customer of HNs, I am a user. If you don't care about your users, then fix that problem, don't try to pretend the word is the problem.
