Informal tagging Thing #13 A First Judgement

I like a formal vocabulary. I like having standarized search terms. I really like having an index where I can discover what search terms are being used. Therefore my automatic judgement of information tagging is that it's not terribly useful from a professional standpoint. I remember in graduate school when Yahoo.com had "categories" so you could limit your search to already sifted areas of the web. I thought it was great when Yahoo.com was using librarians to help "catalog" websites. Informal tagging violates all of this and doesn't necessarily help anyone find anything because we all use slightly different vocabularies; without creating any source where we can discover one another's tagging vocabularies (or what I might have called cataloging terms) the web becomes that more difficult to navigate.
