startupSQUARE attracted (and still attracts) a lot of interesting exchanges. In my habit of responding to as many as possible I often say stupid things. Whether it's on-line or in person, it's a habit.
(Btw: Never ask a woman if she is your friend's mother. Even if you're right, you just told her she looks old.)
One exchange recently caught me by surprise. I was approached by someone (as usual, name redacted) who called themselves a "domainer." Not being familiar with the term (I've been out of the country for a while) I asked,
"What is a domainer?"
