Thank you all for this interesting thread. Ben's idea of a separate website for end-user make sense to me.
Small vision
============
a basic installation with everything under ETP and a frontpage including "chunks" from installed packages (latest news, random pictures, latest posts, rencommended book, ...) + 2 or 3 templates and we would have something enduser could use.
Add to that a forum to help the community fix thing not working and/or customizing.
And some simple howto articles so people interested to spend some time on oacs could start learning how to make small modification (still not meaning programation).
