Soma announced a new project today, the MSDNWiki, which takes our MSDN documentation and adds structured discussions to it, allowing you to see not only the original articles, but conversations about it, other links, etc. While you can't edit the original documentation, the rest is fair game.

This is an interesting approach to melding the unstructured nature of a wiki with the structured nature of a forum. You can add your own feedback, edit it, comment on what others have said and add to their "blocks".

I'm curious as to which people find more useful - and whether that usefulness is different depending on the medium or what you're trying to accomplish. Allowing others to change your forum question may not make sense - but being able to change a "block" in a wiki that is all about documentation may.

What are your thoughts?
