I was continuing to try to decipher the good and bad from the new profile pages, going back and forth between people's profiles to see the difference in UI length when they have empty fields. When I noticed that whenever I got to my profile, there was no back button.

At first I thought this was just because I was clicking in the upper left, then I realized that it doesn't matter what menu I use to get to my profile. Getting back to where I was when checking my profile is kind of just a hassle.

Don't know whether this was intentional, or an oversight, but it's really inconvenient either way.
