WordPress is an amazing piece of software. I've been using it for years and I've constantly been impressed by the ease of use. It's easy to install, it's easy to manage, it's easy to reskin. I *love* the WYSIWYG TinyMCE control. WordPress is great.
These days I've been looking for a wiki worthy of being on the same server as WordPress and I haven't found one. Few support WordPress-like WYSIWYG and that nixes most for my purposes right off the bat. I notice that WordPress uses MediaWiki, but even y'all haven't figured out how to get TinyMCE plugged in there I noticed. Even with it though, it would still be a bit clunky compared to WordPress.
Anyway, I know it's a bit of a stretch, but if you guys ever feel like taking on another project, a WordPress-like wiki would make the world a better place IMHO.
Thank you for your great work on WP!
