I wonder if the mere existence of a blog tips the scale towards E instead of I. That would be based on an extremely common misconception that most people have of introversion on MBTI--namely, that it equates to being shy or private. If I recall from the last time I took the test (administered by MS in clinical psychotherapy, scored almost the complete opposite from Typealyzer), the score differentiators had to do with behavioral responses. I doubt blog writing is a good indicator of actual social behavior.
