Personally, I think the guys, in spite of their perceived arrogance, are quite brilliant and should be given more respect then they have been.

First, the fact that they even came up with the idea (or helped come up with the idea) of Facebook should lend some credit to their ability to be inventive and see where the future is going.

The fact that they see Bitcoin as a worthwhile investment should be taken seriously (based on their past successful ideas) and the fact that they are so bold about it, in spite of the heat they keep taking for it, is a big deal too!  It is not easy being in the public eye and having your every move scrutinized.  I feel for them really and I respect them for that.

Just my thoughts.
