I agree! He shouldn't do what he doesn't feel like doing! If he is not in twitting mood, why should he tweet only in promotional purposes??? He is close enough to us, not like many other stars.
I want to be sure that when he does something to us, communicates with us - it is sincere. Not nice, but kind.
So, people should let him do what he wants, not complain or advise.
