Hi bob3160,
We can discuss if it was related to the verb fail (epic fail moment), because Microsoft failed and because the results were ironically miserable, the IE8 XSS-filter made that secure sites that were not vulnerable before the filter became vulnerable through implementing the filter, and that was the epic part to grant the award. And it was a MS failure also because the intention was good but the end result was miserable, so they got the award both for an epic fail on an XSS filter that was a failure,
by the way the XSS filter of NS has not been beaten and firekeeper is also a very reasonable filter in this respect,
