A site appeared two weeks ago called eduStyle. It is a design gallery that will (hopefully) showcase exemplary higher education websites.
It's a community site, so the number of users probably isn't large enough yet to make the ratings "valid" but that should change if the user base increases.
Users (registration) submit sites, comment, can add tags, and vote on sites in the gallery.
I registered this week and, of course, added the NJIT site.
