I missed PopTech this year. While I was home unpacking my suitcases, conference-goers recharged their minds on the gorgeous coast of Maine. I kept up by watching live streams from the conference, but got the most out of Ethan Zuckerman, who is a master blogger and was posting live during the conference. His post on October 19 led me to We Feel Fine - a site that explores human emotion by providing real time insight into what people are thinking and feeling through a data collection engine. It's simply amazing.
