You might be interested in bloginality, grouping webloggers by MBTI. I'm an ENFJ. The most interesting thing about my MBT is that I have never, ever scored an S (Sensing) in all the times I've taken the test. I'm a pure iNtuitive. This gets me into trouble with things like facts and the real world (via Rudy).

(The visual design over there is pretty annoying, and they're pushing their Amazon Associates links pretty hard, but, like I said, you might find it interesting.)
