These things are where games theory meets game theory. There's a few of these for Social Media and web usage, but none of them seem to work for me. People used to love the Fantasy Football games and this fits in with that kind of thing.

You can't judge these games from the outside, I suppose.

The interface looks nice. I like the look of the ticker which feels very 'real'.

I've seen these prediction markets being used as a teaching technique - usually attracting 'ethical' doubts from commenters.

Is that justified?

I basically don't get these games. Which probably makes me the worst person to play them - or makes me ripe for learning.

Hmmm.
