Consider mixed approaches, too? not just bipolar (closed/open)
Fragment of a discussion from Talk:Quality control in open versus closed approaches to authoring educational resources
[ok, sorry, for my reply I just tested 3 different positions, none of which is actually satisfactory, I feel. Would it have been better without rich text - prefer non-rich-text anyway - I think it is not a good idea to have less fully developed wiki functions on the discussion page. But there most likely were reasons to do it this way - could someone point me to any page I could take this discussion to?]
