Quoted from Helmut's post at http://community.wikidot.com/forum/t-19870#post-50114 :
And about the handbook "content" we ( the starter team) discuss now over a longer time on the two handbook pages:
http://handbook.wikidot.com/en:content
and
http://handbook.wikidot.com/en:content-2
I personnaly prefer version 2, which is more compact.
Moreover, there is a lot of redundancies in the table of en:content
