Almost all presentation bloggers are introverts

A little fun on January 1. I ran the typealyzer test on a number of presentation, speaking and communication blogs tonight.
In case you are unfamiliar with Myers Brigs personality types, you can catch up here, and do a test here.
ISTP - "Mechanics"
Me (!!!) [a bit different from my test results]
ISTJ - "Duty fullfillers"
INTP - "Thinkers"
INTJ - "Scientists"
All of these great communicators are introverts? And now for the only extrovert in the pack:
ENTP - "Visionaires"
It is great to have so many excellent presentation blogs around. I am looking forward to exchanging ideas with you in the new year.
