I too feel a bit sorry for Mike Hearn after reading his write up on the current state of affairs. He is quite right and on the spot on most of his post and one can clearly see he wanted to change something and leave a dent on Bitcoin for the better and that this talk and all of the disregard for a block size increase made him tired.
I think he did well on going away, sad to see he didn't have much of a chance.
He might be right on a few things but he was wrong and spreaded a lot of fud on other things and all because he acted like a baby just because he didn't get his own specific way. Things need to change with bitcoin but just because they're not happening as fast as he would like or in his way doesn't mean to say he should just give up.
