Most of the gnome3 criticism comes of from the fact that it's an unusable mess. It's the most hated environment compared to KDE and Unity and this is the fact. 10min is the time that average user comes to the conclusion: wtf is this?! Gnome people have no clue about usability or their just messing everything up intentionally. There's no even way to configure fonts, so it's not a sane DE.
