Analyzing IM Language

I've started reading this book called "The Definitive Book of Body Language" and it talks all about... well... body language: The non-verbal signs we give, the unconscious things we do while communicating, and how to interpret all of these.

This kind of knowledge could come in very handy for one making a presentation to a client, or those about to undergo a job interview, or those going out on a first date.

Crossing one's legs, twitching eyebrows, stiff upper lips... every little detail tells something about a person.

And this got me thinking: for those of us who chat online (YM, MSN, etc.), or send messages through social networking sites (facebook, twitter, etc.); do we go as far as analyzing the instant messages of our friends, crushes or lovers?

I've been guilty of doing this. What does she mean when she says, "maybe"? Why did she place a smiley after, "see you later"? Does the ?!?!? after the words "What happened to you" mean thatshe cares about me?

Could we study these things like we do body language? Can we catch a glimpse of other's personalities or emotions through online communication? Will emoticons ever truly capture with certainty that which a person wishes to express?

There are huge implications to this, especially if we wish to use instant messages as evidence in criminal or civil cases. Was there malice when he typed, "I could kill you!"? Or does the phrase, "Sige, pay when able ka na lang, pare, hehe," give rise to a valid obligation?

We've mastered body language. Perhaps we can move on to IM language. :p
