Notice how the 11 comes before the ten. This does signify that eleven is, indeed, louder than ten. Everyone loves hating Unity. It's new. It's different. It's pretty. It's everything that Linux typically isn't. People also love hating Ubuntu in general. While people struggle to make their Linux desktops look and feel more like OSX every day and there are over 9000 different OSX-like docks out there, people apparently really hate having something that looks and acts like an OSX desktop. It's very odd.
