Remember QR codes? Six months ago (or was it last year?) they were the flavor of the month for about two weeks, they were about as "drive by" as you can get.
The problem with capitalizing on the latest craze, such as houzz two years ago, Pinterst today and whatever comes along tomorrow is that the people you find there aren't there for you. They're there to be a part of the latest craze. And no matter how much you invest in that latest craze as soon as the next big thing comes along you'll need to start from scratch because they'll be gone and you'll have to run to keep up.
