This is a great read, the author certainly has the dry type of humor that appeals to me.
I’m glad to see that the article ended with a “Don’t worry to much about it” attitude. The same factors that keep us from reaching metadata enlightenment are present in just about all human endeavors and it hasn’t been to devastating yet.
It is good, however, to keep these aspects of human nature in mind when reviewing your or someone else’s metadata. I’m reminded of the biases that we as a profession have inherited with certain legacy aspects of our field. Just take a look at how the three hundreds section of Dewey is broken down or look at the changes that were needed to be made and still need to be made to the library of congress subject headings. It would be pretty easy, particularly with more open-ended metadata content such as descriptions, to misrepresent the item being described.
