It is tragic that some people have apparently found it too hard to edit
the wiki. I do not consider this to be inherent in a wiki though. I do
perceive this as an indication that the wiki should be made more
accessible/integrated better and clearer help should be given (as would
be necessary with /any/ system like we're discussing).

So why not simply move most of our site over to the wiki? Then we can
reorganize and restyle that, making sure that it becomes easier to
navigate and contribute. That way our site becomes more accessible and
better orgaized, while still getting the advantage of being able to
easily edit it.

Keep in mind that Inkscape relies on voluntary contributions. This means
that whatever system we have, it should ideally be an "out-of-the-box"
solution, have a very low barrier to entry and require as little
maintenance as possible, while still allowing for structure and complex
content. (To me this spells wiki, especially since we already have one
ready to go.)
