The reasons why Facebook doesn't improve its horrible interface have to do with incredible technical bloat, and their userbase being stringently resistant to change. It's the type of person who won't start using something else until what they have doesn't work at all anymore. I predict an exodus if they tried to modernise. Even so much as flattening out some of those beveled edges and gradients would be enough to throw people off. "Ugly and messy" doesn't have to be a part of the equation when what you want is "dense." It's possible to have minimal, clean, dense design. With lots of buttons and features, beneath a simple UI.
