OTOH, the currenty wikipages are not really suited to discussions at all - I'd rather not have someone edit my "posts" - whether it be for fixing the speling or whatever.
Well, I for one would object to any system that doesn't allow me to edit other people's comments. It's too useful to let traditionalism and conservatism ruin it. It's not just about fixing atrocious spellings, it's also about removing objectionable parts of comments without removing the entire comment, or about summarising an unnecessarily long piece of prose. I don't see any point in listing the advantages here since wikis have shown time and again that they work, and Wikipedia wasn't the first. Yes, it defies the well-established and widely loved web forum paradigm where everyone "owns" their own comments, but we're not a web forum, we're a wiki, and wiki is our paradigm.
