A couple of OT thoughts... 1) It was very odd seeing something go from the HN "new" page, to the front page, to seeing people talk about it on twitter, to hearing about it from friends who have no idea what a "github" is, to my mom asking me to help her download this new game all her friends are playing. I still don't know how I feel about it. And yes, for some reason I feel like I have some sort of ownership simply…
I think #5 is wrong. 2048 is based on numbers but has very little to do with math--you can play the game just as easily using only colors. At best students are learning the powers of two, and at worst they're wasting time they should've spent on chess or checkers, or basketball.
(but yes, learning the powers of two is only a tiny fraction of math)
