I never get tired of these stories where people change their digital habits.

Understanding the often hidden architecture of our tech environment helps us make mindful decisions. A couple other posts in this genre I've enjoyed lately: Bye, Bye, Google by Bogdan Popa and Pulling the plug on Facebook by Drupal founder Dries Buytaert.
