There's a melancholy in watching software die. One day, it's the tool you swear by, shaping your work and your life. The next, it's sunsetted, acquired and dismantled, or quietly abandoned in a forgotten GitHub repo. If you've been on the internet long enough, you've buried many of your digital companions, such as del.icio.us, Google Reader, ICQ, Winamp, and countless others that once felt eternal.
