Per category privilege = WP as a portal CMS
One thing would make WP finally a good candidate for people wanting to use it as a collaborative & community CMS : adding per category privilege.
What's a collaborative & community site ? It's like a short news page, a lengthier articles page, member columns, a forum.
Now imagine you have a wordpress powered site (shouldnt be hard to imagine :) and you create 4 main categories : News, Articles, Columns, Forum, and subcategories if desired.
Now create the following privilege : say Level 9 (site admins) can post in "News", Level 8 (site helpers) can post in "Articles", Level 3 (trusted users) can write in Columns, and Level 0 (anybody registered) can post in Forums.
Now it's just a matter of rather easy php & sql coding to arrange an index.php that shows news, that lists last "Forums" threads and so on just as any *nuke or portal ware.
Any comments on this ?
