I have no beef with gtk/gnome and the like, but I find it really funny when developers use such colorful language.
Still, as a heavy terminal user, I fail to understand what's the big deal with the choice of terminal. I have used only xterm for more than 20 years (with a short stint with gnome-terminal, and I didn't find any relevant difference). It starts instantaneously and doesn't make any fuss while it's running. Is there anything important that I'm losing?
