I remember hearing one of the founders talking about users trading stocks. He explained their data shows people get better at trading stocks with more experience. I can't remember the source, but I think it was on This Week in Startups podcast. This is really suspect--kind of like a casino telling blackjack players they will get better the more they play.
If Robinhood is incentivizing or encouraging frequent trading by users, that's not really good in my opinion. It doesn't make them worse than other brokerages, but it doesn't make them better either. And with a name like Robinhood, they are positioning themselves as white knights.
