You get to keep it.

That's hella cool.

This post makes me want to work at Mozilla!

I did another internship for enhanced experience, but I'm going to have to consider it myself one of these years. :)

(The pay is also great and the other perks and location are amazing.)

That just means it becomes taxable income.

Never thought of it like that - that's interesting.
