Follow-up: I Twitter, Therefore I am not a Twit but a Savvy Chick!

My initial foray into the world of Twitter or "twittering" was started with some degree of trepidation and confusion about this popular medium of social digital communication. I had reservations because it simply did not strike me as an effective way to hold quick chats; something, I believed, instant messaging was purported to do quite well for the attention-span-of-a-gnat crowd.

What was the method to this madness of sending out seemingly random thoughts? What compelled total strangers to share the inane contents of the short-circuits popping off their brains? Why was "everyone" catching the wave of dispensing with much flourish, their @whatever twitter handles at the drop of a hat with the exhortation - " tweet me?"
I was curious and wanted logical not pat answers to my questions. So I signed up anyway because some of my friends, people I love and respect, were on it, loving it, and regaling me with stories about how some elusive marketing/business/creative/ridiculously successful whiz had just responded to their tweets and was now a follower and vise versa.
