This might be the best Hacker News comment I have ever read. Excelsior.

Start talking about your children and your audience will be hoping you move onto your IQ.

I would agree. I said it in direct response to someone pointing out his IQ of 150. I was making a point... Or would you say that it's OK to talk about someone ELSE'S IQ?

I also suspect that people would rather not know your phallus size or six+ figure income. All these things are left to discover as a side effect of normal interactions ;)
