Closing the about me window to reach the achievements and stories links was unintuitive for me. (also perhaps consider having clicking outside one of the story events close the story (the same as clicking outside the about me and contact me panes), scrolling back up to the x wasn't that bad but my first instinct was to click on the background.)
I am also unsure why the achievements / stories buttons switch between the two as they don't overlap, I understand not wanting to have too much showing at once, put perhaps a pan on the background or something (not a fully fleshed out thought).
