Here’s a pretty interesting tool, as more people are online on Twitter.

Dan Zarrella, a social and viral marketing guru, has come up with TweetPsych (via TwiTip), a site that can build one’s psychological profile based on the content of their Tweets.

As he states on his blog, “Communication is a window into a person’s mind, and the way a person talks can tell you a lot about how they think.” And to that goal, his tool relies on Regressive Imagery Dictionary and the Linguistic Inquiry and Word Count. The first scheme “is designed to measure the amount and type of three categories of content: primordial (the unconscious way you think, like in dreams), conceptual (logical and rational though) and emotional,” while the second, “measures the cognitive and emotional properties of a person based on the words they use.”

Give it a try, and see what kind of person you are, based on how you use Twitter.
