Maintaining control of our data with personal databases | N=1 (marcua’s blog)

The fundamental problem is that in using most modern consumer-oriented applications, we lose control of the data we share with those applications. In creating documents, writing emails, or tracking our exercise or other activities, we share data with an application that’s useful for a particular purpose, but also allow the data live in a database controlled by the application’s owner. With the data outside of our control, it can then be restricted, lost, leaked, sold, resold, and exploited. The groups that control these databases accrue most of the benefits, and we accrue most of the costs.
