I'm willing to move every simple textual (static content) page from the website to the Wiki and link from the website to the corresponding pages.
I think this is a bad idea.
The current system ensures that changes to the core parts of WineHQ are reviewed before being made, whereas a Wiki can allow things to change willy-nilly, often reflecting the views of the last person to touch a page, rather than a consensus.
For things that are relatively fluid, like statii and such, I think the Wiki makes great sense. But for things that are, essentially, static, I think the current static web site works fine.
Cheers,
Jeremy
