I think in part the 2001 attacks have been eclipsed by the 2012 embassy attacks, at least in the realm of active responses from readers.
For myself, there are certain almost-rituals I do annually, to both refresh my own memory, and to share and explain that day to my children, all of whom were born after 9/11/01.
It was only this year, that I finally wrote down my own remembrances of that day. Perhaps memory would have been sharper had I done it sooner, but I think I have a better perspective on it now, 11 years later.
FYI, I was in Kansas at the time. Just so no one mistakenly assumes I was in NYC or DC.
good stuff - now with a dead ambassador in Libya we can call 911 teh continuing series of Attacks on America.
