This is a good example of a Subject Guide, in this case for Business, in the format of a Wiki. There are nice touches like the Meebo box and "Featured" articles on the home page. The author, Chad Boeninger calls it an "experiment with an alternative form of delivery of library information".

It's interesting that he's also enabled the "editing" feature so that others, potentially at least, can add to the site.
