That still seems like an curious criterion with which to judge someone's humanity. Gary Vaynerchuk, DHH, Zed Shaw, and a lot of the people admired by many HNers are very self-aggrandizing.

Sidenote: It seems that people like this have to deal with a trough on their way up where a lot of judgment gets thrown their way for their outgoing manner. If they hit it big, though, that seems to be quickly forgotten and everyone loves them. We've seen it with all of the above. Those who fail to cross the trough, end up forgotten.
