OK I'll bite, why is the usage so high? Is it people lurking to find out if Twitter really is going to die?
Also what does he mean by "usage"? Does he mean tweets sent? I know that a lot of people are freaking out thinking their accounts are going to be closed.
Of course Twitter usage is at an all time high, Elon and Twitter are front page news everyday, it's the hot topic. He probably closed the office for a headline because it's free PR
