The first limits automation (if true).
I'm not primarily concerned with automation as much as easy of use. In my experience, it's easier to link to a page using markup (e.g. "If you use [[Power Attack]]..") than to use a WYSIWYG editor.
As I understand it, Wetpaint does not allow linking to non-existing pages. On a regular wiki, a list on wanted pages is a great way to see what needs to be done. This means that you need to back to existing pages and add the links manually. This will mean a lot of work if the SRD or other content is to be added to the site.
IMO Incorporating the SRD is a good idea. This will hopefully result in a wiki version of
Hypertext SRD, but with Mongoose and hopefully other OGL content. Note that several wikis with SRD (and some fan OGL content) exist, so SRD wiki markup is already available.
Of course, having PDF file downloads as well as wiki pages would be nice, but a fully linked gaming wiki is a thing of beauty. Hopefully such a community OGL wiki will include the SRD, published OGL material, and fan contributions.
I'm not involved with
dandwiki.com or
d20wiki.com, but those sites have been very useful. (Yes, I've copied OGL wiki markup to my own wiki

) I'm not saying that this project should join one of the existing wikis, but I'm sure they would approve of Mongoose releasing published material to the community.
One benefit of using MediaWiki markup (regardless of MediaWiki hosting service) is that it will be easy to exchange content with the existing OGL/SRD wikis.
