SAN FRANCISCO: The second floor of the Moscone Center was hoppin’, quite literally, all three days during Macworld / iWorld. There was a DJ spinning tunes and people dancing. It had all the makings of a party except…there was no sound. What does this have to do with the Mac or iOS you ask? Well, that’s a good question because it really doesn’t. Just one example of why people are calling the 2012 Macworld a weird one. But that didn’t stop this group of Apple fans from having fun with it. Here’s a video I took of this crazy phenomenon.
