I found this fascinating. Wolf works hard to humanize the "tracking" phenomenon, and I think he makes a convincing case that careful tracking, coupled with sound observation and experimentation, can help us get to know, and improve, our true selves.

Insightful report on the emerging trend of personal data tracking. Author Gary Wolf visits over a dozen pioneering trackers, who are analyzing their personal lives with a variety of tools, from written diaries to electronic sensors, email and social networks. This in-depth article is factual and well-researched, citing many credible sources to provide an informative overview of this new field -- with a thoughtful analysis on how it might impact society.

An interesting collection of anecdotes, but the sum of the parts isn't overly meaningful. The overall idea – that data collection is increasingly prevalent in our lives, and can be used to unpredicted benefits – is important. Unique anecdotes are an interesting but not particularly effective way to tell the story.

A lengthy piece describing how we're captivated by technology. Science gives us speed, but taken away our emotions. I really like this piece, and spent some of my valuable time in reading this. Thanks to NYT and Gary Wolf for the insights.

This is probably one of the most interesting articles I have read in a while. Well researched and well thought out. This has got to be one of my favorite articles of all time!
