But did you consider how other people were viewing your user page? :P Your user page may have appeared neat to you, with your monitor resolution and settings, but may have looked a mess to everyone else.

Personally, I don't mind whether it's fixed or not. In the old look, I just spent a couple of minutes extra making sure designs weren't looking awful on other kinds of screen widths.
