Do you think that invisible metadata is generally preferable to the  
visible kind? No better or worse? Or is visible metadata often  
better? Keep in mind these principles are guidelines and few are  
absolutely inviolate.

I think it would be hard to argue that invisible metadata is  
preferable, or even equally good. Companies that make a business out  
of organizing information on the web do not generally give weight to  
information that isn't presented to the user. I don't think your  
anecdote outweighs this evidence.
