Hey there.
I've been looking for some kind of Wiki or CMS for quite some while now, but still haven't found any that suit my needs, so I figured I could just as well go ahead and ask.

What I need, is a Wiki where you can fully "rate" on the articles. So, say, someone writes an article about "Flowers". People can then vote on certain aspects of that article, like "writing style", "length", "readability" etc.
On something similar to a frontpage would then be boxes ala "Top 10 Readable Articles"

There are a few more specific things I'd need, but I would be able to work around these. What is really important for me is the above rating.

The Wiki naturally doesn't need to support that by default. If there's a good one which gains this functionality through a plugin/addon, that'd suit me fine, too.

Thanks in advance for any help you guys can provide.
