Have we forgotten about September 11th?

I worked yesterday (at movie gallery for all of those that don't know). When people sign up for a new membership they have to sign a membership agreement, which includes dating it. Almost everyone that signed one didn't know what date it was. You'd think that most people would at least know when it was Sept. 11. (One guy, after asking me the date, even wrote 2004, but thats another story). So, that lead me to question whether people have already forgotten that tragedy that happened just four years ago. Wow, what a different time it was, the country united against a single cause, none of this political bickering, which seems worse today than ever before. There didn't even seem to be much media coverage of the September 11th memorials yesterday. Of course, this is mostly because of the Katrina coverage. But regardless, it just seems like people have forgotten, just four years after everyone was saying "we will never forget."
