Just a little comment: wouldn't it help to move the list of licenses at the bottom of the page? The second paragraph says "For the impatients": IMHO it should be first section after the introduction. After all the details of the various licenses are useful only for those that already know the very basics (which you give later in the paper).
If we move the license list at the bottom, people interested in a list of existing license will probably think it's not there. And *most* people will come to see the list and nothing else.
The chapter named "For the impatient" is potentially dangerous (suggesting people not to think is a bad idea in general :-). I'm still unsure if we should keep it or not, if the advices it lists are useful or useless. That's why I did put it after the list. When it proves to be useful, agreed upon by most people, we could move it upfront. If it turns out that it's just a bad idea we will just remove it.
There is the option to make two pages instead of a single one.
Cheers,
