Just a couple of ideas..
1) Would it be possible to create a "Requested Article" page on the community Ubuntu documentation? It would help to be able to have a central location to point out areas where documentation is weak or missing. Then we could have a sort of "to-do" list for documentation, and people who have a good understanding in some specific area could help out by tackling some of those articles. I was thinking of something along the lines of wikipedia's Requested Articles page (http://en.wikipedia.org/wiki/Wikipedia:Requested_articles).
2) Similarly, it would be neat if their were a page or system for suggesting new features for ubunutu, or some part of ubuntu itself. Of course it would be impossible to meet everyone's request, but at least this way we could get some kind of idea of what people want, and make it easy for people with particularly good ideas to get them out before they forget :)
For (2) there is <https:/
