While I'm at work and bored I'll ask it to quiz me on things. I only answer if I'm sure of my answer because it often marks incorrect answerd as correct.

Sometimes I just paste in long randomly generated text in because i hate Microsoft.

If I'm at home.working on a project I will gmuse it to help explain coding things and point me in the right direction. Its incredible for learning programming in my opinion. Very good at explaining things and finding simple bugs. Its dogshit at writing programs longer than a few functions.
