Hey tech heads! Get on Reddit.com right now — Bill Gates is doing an AMA (Ask Me Anything). Now is your change to ask for a loan, or why Microsoft’s smartphone sucks or who in their right mind names anything “Bing.”The chatter started at 1:45 EST and will last until the man gets tired of typing. Or until he decides to go dive back into his stacks of gold, Scrooge McDuck-style. Either way, something interesting is doubtless to develop before he does.
