"Flash Crash" analysis: HFT algos using DoS

Was going to post this here, you beat me :)

I'm a beginner when it comes to financial/economics stuff, but i still found this may 6th crash and the HFT evolution quite interesting. This seems to be the first real attempt at exploiting the exchanges using a computer infrastructure, and the incredible thing is that the ones who should instantly block this with regulations seems puzzled and unable to react. Are we beginning to see in the real world things shown previously only in work of fiction like Daemon by Suarez? Amazing, will follow the evolution of this story in the future...
