Right. And, unsupervised learning can be useful in some areas. Does anybody know how Google news works? It seems to work reasonably well, and seems to be solving the same problem.
Also note that for most purposes however classification is becoming less of a big deal. Read Clay Shirky's article to understand why. Shirkey talks about ontologies specifically, but the gist is the same -- basically, tagging each and every word isn't as crazy an idea if the end goal is just "I want to find something related" which is the most common case.
