Recording personal data isn’t new, but the ease with which data can be recorded, organized and displayed for analysis is. And it’s gaining in popularity. New websites and apps that help people monitor their habits, feelings and behaviors are being released every day. According to the New York Times Magazine article, The Data-Driven Life, over one million people are on the geo-tracking site Foursquare and over 30,000 personal tracking projects are started every month on MedHelp.

Self-improvement and self-insight
People track their data to aid in progress toward goals such as quitting smoking, losing weight or being more productive. Seeing the raw data removes some of the emotion from the process of change and can also, over time, offer personal insight into correlations between activities, moods and outcomes.

Community
With the popularity of Facebook and Twitter, people don’t seem to have many qualms about sharing their data. Many online communities are built around the exchange of personal data. For example, creating a profile on a dieting site that publishes your food intake, exercise patterns and weight loss progress for like-minded individuals to view. Or personal data can be published manually via Twitter or Facebook (tweet your breakfast) or automatically (check in at the Pizza Parlor via Gowala). The social aspect of the web actually promotes the collection of personal data. From The Data-Driven Life:

“The more they want to share, the more they want to have something to share.” Personal data are ideally suited to a social life of sharing. You might not always have something to say, but you always have a number to report.”

Where is this all headed?
In this fascinating video, Carnegie Mellon Professor Jesse Schell talks about how score keeping and tracking devices will creep further into our everyday lives (skip to the 20:00 mark if you are short on time). Sensors will get smaller, more powerful and be embedded everywhere. Just brushed your teeth? The sensor in your brush awards you 10 points. Brush twice a day for a week? You’ve earned a bonus – redeem your points for a toothpaste coupon.

But can you trust companies with this much information?  
It’s all well and good as long as they are using your data so sell you things you want. But what happens when your grocery store threatens to use your buying habits against you in a legal case? Or maybe your health insurer offers them big money for your data — could your rates go up because you buy too much junk food?

In summary
If recording your personal data benefits you in some way, do it. Enjoy the insights and benefits the modern technology can provide. Just be aware that your data may not always be private and you should be selective about what you record.
