After more than three years of participating in StackOverflow, I finally figured out why this gray area to the right of my profile page was not working.
I assumed it was supposed to show a diagram of reputation or something. At some point I think I even submitted a bug report about it. Now instead it turns out, it was in fact working all the time - it was just not telling me about it!
This gray, square area was in fact trying, in it its own little non-intuitive way to tell me "-You have not entered anything in the About Me field on your profile". #UsabilityFail #Nyan
