The look of the site hasn't really changed since 1998, but a major revamp of the site is almost done. Most of the basic functionality is pretty much the same, but some new functionality is there too.
User Profiles
Users can write information about themselves in a profile for others to see. You'll be able to see what other reviews that person has written. New comments will all be associated with a username, so you'll be able to get a sense of what that person's judgement is like.
Message Board
If you're here, then you already know about the message board. It will be a nice place for students to ask each other questions, and maybe even some instructors might participate in the discussions. Who knows?
User Logins
So far the biggest change is that users will be required to log in before they can post a review. Abusive, non-constructive posts have been so common that it has made this step necessary. But this will have the added bonus of being able to associate comments with users so you can get a feel for which writers you prefer and which are less reliable.
If you haven't found it through Google already, you can visit this new site at
http://www.goodbadtenured.com/beta/. Keep in mind that it is still in development, so from time to time you may notice broken pages or some strange table layouts. These will be temporary as I get the site closer to the finish line. Feel free to point out anything that needs improvement!
