There has to be some sweet, sweet irony in the idea being explored that high-frequency traders may have caused the NASDAQ breakage.

From an HN post earlier today (http://www.nanex.net/aqck/3099.html):

"...In brief, the problem was that the system took two extra milliseconds to calculate the opening price. Because of a decision before to allow continuous order placement during IPOs, cancellations kept “fitting in between the raindrops”, in the words of Bob Greifeld, Nasdaq’s chief executive, in the five milliseconds it was taking to determine a price."
