b) I used to like Scribes very much, until I realized one thing: GEdit can do everything Scribes can do, plus much more. It's more mature, and more active. Also, its template system (which is Scribes' flagship feature) is more robust.
Most people don't know how powerful GEdit really is. Take a look at http://live.gnome.org/Gedit/Plugins to get a feel for what GEdit can really do.
Also, Scribes isn't only a Python-editor, unlike what the title suggests (maybe I'm reading it wrong).
So far I like Kate the best, but it's dog slow to open. Someday I should bite the bullet and learn VIM I guess.
Start today, it's an investment that will pay off big in the long run.
The demographic that might be looking for such an easy to use application will probably be using Ubuntu. Most of the other users will be using vi/vim, emacs (don't start it) on the command line on numerous different persuasions of *nix
