Something I can't understand...

Why is this happening? How is it possible that twitter is getting popular? Perhaps there is more to this site than I am seeing, but from the looks of it, it is just a site where you update your status message, yet everyone wants to be "the next twitter". I guess this just reassures my theory that all that really matters is if you can get hype. My new plan is to build something really simple and then promote it like none other.
