It’s 
September the 11th, and look at the CNN’s frontpage of their website! Just a link to the memorials. I’m shocked.
Alan (and Alfons in the comments) has a brief posting about that specific day. I do recall everything too, including my first thoughts. I also remember receiving e-mails, e-mails that seem to have disappeared. The archives in my e-mailer of choice at that time (Eudora) literally stop at the date of 09/11/2001: my e-mailer of choice afterwards only contains e-mails that start at and around October of that same year. What I do remember werethe arguments after the 9/11 tragedy: the Americans I considered to be friends turned out to be bloodthirsty and out for revenge. So much for Afghanistan, Iraq and winning the War on Terror.
Anyways, I myself decided to watch a set of DVDs of Battlestar Galactica (the 80s series), which was probably more sobering than watching members of the administration commemorate 9-11.
