Then someone posted yesterday, I thought it was Scoble, and commented that he uses Twitter because it gives him an eye inside the mind of early adopters. Now that is useful. So I set up my account and to be honest, itâ€™s addicting. [source]
And so like him, I went on and created my account, added up a few friends and amidst knowing what everyone does on an hourly basis (so far, everyone on my list thought 300 was WOW) but I also have some occasional gems like knowing when Leo Laporte uploads his TWiT podcasts and know when Chris Pirillo asks for feedback on tech events such as the recent SxSW conference.
Why Twitter Works:
It gives an eye inside the mind of early adopters. Aaron explained this already.
It can replace live-blogging. It is much faster and easier to do live twittering as all you will need is a phone connected to GMail chat
It is cheaper than SMS. Similar to how people in the Philippines (the SMS capital of the world) use web based applications for SMS such as Chikka, Twitter can work the same way as long as you and your friends are configured to receive messages only from each other.
It can be so useless to the point that its engaging. I remember my old literature professor talking about how useless literature and the arts can be — but then he added that “in the most useless of things can you find the most profound lessons.”
