Guys, calm down! I don't understand what your problem seems to be. Seriously.
I didn't ask anyone to start documenting everything while I would be waiting until everything is finished. Neither does anyone wants to take away your beloved framework. I just thought I could ask if people are actually interested in more documentation (see my initial post!). I guess there is no need to discuss this in anyway. If you are comfortable without documentation, don't waste your time flaming here that you don't give a s**t about comments.
Right now there are seven votes for the ticket
against the three rather negative comments here. So as for now I would say "people" do like documentation.
As for "you start doing it", since I'm currently working with andengine I definitely would contribute some documentation. But to be honest, I would feel better if there would be some people willing to do the same. Otherwise it wouldn't make much sense I guess (especially because I just started using the framework and won't use all parts of it).
So my idea would to start a clone of andengine just for the documentation. Everybody could contribute. And at some point we would ask Nicolas to merge (or do something else, like just linking to the documented version).
