Wow! What a spay - full of bile. By all means, haters gonna hate. If nothing else, his blog post proves that.
In the meantime, the rest of us are trying to point out real usability regressions in Gnome 3.
Like complete loss of desktop visibility. Like the fact that it takes significantly more mouse/GUI actions to change a workspace or start and app. Like the fact that any real remote work is no longer possible with shell/llvmpipe. Like the fact that minimised windows going into oblivion is nonsense on a system where everything must be a GUI metaphor for something. And so on and so forth.
