Today is the last day of 2009. This is a particularly exciting and bittersweet time, as it marks the end of a curious life-tracking experiment I began on the first day of the year.

In addition to the wallet, keys and phone, I made sure all year to always be stocked with numerous 2009 Annual Report cards. These individually numbered cards were handed to any person with whom I had a meaningful encounter this year. They invited the recipient to visit a survey page at feltron.com to answer questions about my mood, our relationship and activities together.

The conceit of this year’s report is that it is a crowd-sourced collaboration by friends, family, colleagues and new aquaintances. I have received over 500 responses so far and am impatiently awaiting the end of the year to tackle this messy but insightful data set. To everyone who participated and tolerated this experiment – I am incredibly indebted to your patience and hope to make the most of your responses over the next few weeks.

Thank you again and have a happy New Year, Nicholas.
