Comment of yours from the thread you linked:

Sounds like you're not only asking why it is exciting, but you're also making a useless, mean, possibly offensive comment about art studies.

Why did you need to say "poor art students" and "will never have careers"? Certainly, the HN crowd don't like snarky/mean comments like that, it's why it's in the community rules.
