I've said this before, but I think QR codes are useless. You see them everywhere, but the thing is, they take you to something that's not even optimized for your mobile phone. They don't help me get from Point A to Point B. It DOES however, get me to somewhere in between.
On the other hand, we have Shazam. The team behind Shazam did exactly what I was hoping someone would do. They made it extremely EASY for users to become more engaged. It's one app with MULTIPLE uses. It doesn't make the process DIFFICULT. It's STREAMLINED, and connects you to all your favorite social media services. Not saying scanning something isn't difficult, but in my opinion it's far easier to whip out your phone and Shazam something. Also, let's be honest here, QR Codes simply do not look nice at all. They take up space, and are just unpleasant to look at. Hoping to see more of Shazam and less of this QR business.
