Slate has a nice short (4 minute) interview with Nicholas Felton, creator of the annual Feltron report that always makes waves in infographics and visualization circles.

New York graphic designer Nicholas Felton tracks where he goes, what he eats, and a million other tiny details about his daily life. Then he packages the data in beautiful annual reports. The publications used to be aimed just at friends and family, but now you can see them too.

The interview gets into a few of the social details like how much time he spends tracking the data, and the various tools he uses to keep up with it.  Hint: He makes liberal use of an iPhone Calendar (shown above on his desktop).  He also uses the FitBit, which I’m really excited to see how that turns out in his 2010 Annual Report.
