You do realize you are criticizing the topmost user interface details of a theme of an extensively themable early release. I think those "spare-time developers" have been focusing their attention on the API changes that the Gnome 2 to 3 transition impose and the new concepts introduced by the shell. The core seems very good. What you complain about is usually addressed in the configuration files for the theme and the names of the shortcuts. Multi-lingual support will bring some additional problems that should be addressed in the coming weeks. There are many dozen different themes that are compatible with Gnome. All those will have to be tweaked to look right.
Have a little more faith, for just about every computer that is responsible for your internet access runs on top of software written by people you would call "part-time programmers".
I'd trust their work over the one from Microsoft's full-time employees anytime.
