The ubiquitous Facebook ‘Like’ button has come to Diesel stores.  Scan the QR code on jeans in-store with your handset and send a Like with a product shot to your friends.  Would be nice if the Like had a call to action – such as an incentive to buy – online or in-store, but its a neat innovation nonetheless.  Think we’ll be seeing a lot more SoLoMo (social – location-aware – mobile) technology such as this driving social commerce innovation.
