Not sure how I missed this, but I just came across the EDUCAUSE | Blogs site-within-a-site while surfing Feedster to get the latest stuff from the Educause 2004 conference.
I had no idea that Cyprien Lomas was blogging - met him at the NMC2004 Summer Conference at 2004, and I'll definitely be following his blog...
The Educause Blog site looks to be pretty much what a department would need to use in order to officially adopt blogging as part of their website - a collection of bloggers and categories, with the ability to view individual bloggers or categories, or collections of any combination thereof. Very nice. They don't say what software they're using, so I don't know if it's WP, MT, or if they rolled their own...
