High Frequency Trading
I think the long term investor is not too much affected by things like the flash crash. That said, I think it is very stupid to allow a system to evolve where half of the trading is a bunch of short term people trying to get information one millionth of a nanosecond ahead of somebody else.

It’s legalized front-running. I think it is basically evil and I don’t think it should have ever been allowed to reach the size that it did. Why should all of us pay a little group of people to engage in legalized front-running of our orders?
