Free time. I used to use it to sleep, read books, listen to music, watch movies, play video games, do laundry, exercise, talk to my family, and cook my own food. I can do some of those things on the commute to and from work with apps, but it's not the same as when I had free time. I think google or facebook bought it and quietly obsoleted it in 2006. I'm still looking for a replacement. Someone suggested Activity Blocks or HabitRPG, but they don't work the same.
