Typealyzer seems to be a pretty good gadget to estimate the personality of bloggers, at least in comparison with many other gadgets that seem to produce rubbish. When I entered motls.blogspot.com, it said the following:
INTP - The Thinkers
The logical and analytical type. They are especialy attuned to difficult creative and intellectual challenges and always look for something more complex to dig into. They are great at finding subtle connections between things and imagine far-reaching implications.
They enjoy working with complex things using a lot of concepts and imaginative models of reality. Since they are not very good at seeing and understanding the needs of other people, they might come across as arrogant, impatient and insensitive to people that need some time to understand what they are talking about.
(That sounds pretty sensible. The two paragraphs above forgot to mention that I am right and those "other people" are wrong. ;-) The website also showed a map of the brain with an "active triangle", indicating most activity in the logic/mathematics corner and significant activity in the intuition/imagination/symbols corner, too. Sensing wasn't quite turned off, either.)
