This was modded down, possibly for incomprehensibility, but... is the Khan academy planning on hiring any profs?

Is it still the one dude doing all the videos?

Well I don't know about others, but I moded it down because it was "jerk-like" behaviour. The same comment could have been written in a polite and professional manner, but the op chose to write in an insulting manner.

Following the recent thread on HN quality, I've decided to be much more aggressive in downvoting impolite comments.

"Insulting" is a gross exaggeration. That's this forum's style! Where do you think I’ve learned it from?

You and the parent both admit that I have a point. That’s good enough for me.
