Bloom's taxonomy is really not helping us develop education, even if it can act as a memory aid for a person who really have not thought at all about different types of knowledge. But then there's a risk that the image of the pyramid stays in that person's mind as The Model of Knowledge.
If someone wants to use the taxonomy, I would recommend the revised version by Anderson and Krathwohl from 2001. Krathwohl was a member of the original group who developed the taxonomy in the fifties.
You can see a comparison of the old and the revised taxonomy at: http://www.coe.uga.edu/epltt/bloom.htm
