Thanks to Jos of RRS - Look to Windward for referring me to Typealyzer, a site which promises to determine your personality through your blog. You just give it the URL of your blog and it responds with a personality analysis.
Here is what it came up for me...
The active and playful type. They are especially attuned to people and things around them and often full of energy, talking, joking and engaging in physical out-door activities.
The Doers are happiest with action-filled work which craves their full attention and focus. They might be very impulsive and more keen on starting something new than following it through. They might have a problem with sitting still or remaining inactive for any period of time.
It seems that the answers are based on the well-known Myers-Briggs personality assessment tool which assesses people on four pairs of "preferences".
But here's what is really weird. According to Typealyzer's analysis of my blog I am ESTP. But every time I (the real person me, not my blog) have filled out a Myers-Briggs questionnaire I have come out as INTJ, in other words exactly the opposite on 3 of the 4 dimensions.
What does this mean? Is "Tillerman" not the real me? Am I playing a role when writing my blog? Am I exploring a hidden side of my personality that doesn't usually appear? Is sailing (the main subject of my blog) an activity in which I escape the "real me" and become a totally different personality? Are you a different personality as a sailor and/or blogger from who you are in the rest of your life? Or is Typealyzer total crap?
Try Typealyzer yourself. What do you think?
