where were you mashup

Where were you on 9/11? I was at CTIA Wireless IT in San Deigo and it feels like it was just yesterday. Related to this, I stumbled onto a nifty mashup on platial that is titled where were you on 9/11. the app use google maps to enable users to share their experiences from 9/11. An interesting concept in social networking from platial.. nice stuff. See Ed's map at http://www.platial.com/edshepp/map/2968
