Nick: 80% of #Gnome users install extensions...
Me: 80% of Gnome users are wrong and/or don't know how to use it.

In all seriousness @thelinuxEXP, Gnome's layout is unique not only in the Linux world, but also among every other OS/platform. The most popular extensions that people tend to install change that layout to add a windows-like panel or a Mac-like dock. Both are antithetical to how Gnome should be used, and there is a correct way to use it. It's a rather opinionated UI.
