Twitter is the dumbest

Just when I thought I was the only one to think that twitter was the dumbest and most useless web 2.0 app, I saw this video.
They took my thoughts and definitely ran with them. I signed up for twitter possibly a year ago before it really got super popular, but it has since passed me by. For some reason, I could give a shit less about what everyone is doing all day everyday. What do u think of twitter?
