Eleven years ago today, America was attacked. It is 9/11, looking at the date gives most people shivers. It feels like yesterday but it was 11 years ago.
Typically, the search engines pay tribute to 9/11 by changing their home pages in one way or another. Some do subtle things like add ribbons, while others go more extreme with a full home page change.
Here is how Google, Bing and DogPile remembered 9/11 this year, where Yahoo seems to have not done a thing for the day.
Google 9/11/2012:

Bing 9/11/2012:

DogPile 9/11/2012:

Ask.com 9/11/2012:

Search Engine Roundtable 9/11/2012:

I am not sure why Yahoo didn't add a ribbon or something. Last year, the whole home page header went black. This year, seems like nothing. At least right now.
There is one complaint about Google is using a black ribbon in the Google Web Search Help forums but it seems crazy to me.

Google's is quite disappointing considering the big deal they make out of every other holiday noone has ever heard of.

If that is the best Google can do, then you have to question their loyalties. it's clear that Google has it's priorities messed up. Disgusting.

If they don't keep it simple, SOMEONE will find something wrong with it. You're pissed off at a ribbon? This day means more than that. Go outside and love life. That's what days like this are about.

Relax... it seems everyone is more worried about who "remembered it better" than simply reflecting and remembering it themselves in their own way.

Apparently Marissa is already differentiating Yahoo from the crowd: Hey we're Yahoo damnit! No time for reflection here!
