Pinterest has unveiled a new feature that will find you a recipe with just a click of your smartphone's camera: "Dish recognition."

I honestly expected these all to be Pinterest fails. There are so many gorgeous Easter egg techniques out there -- and so many Pinterest tricks that fall flat -- that I was shocked these seven actually worked.

Now that Facebook has entrenched itself it can be difficult for smaller social networks to gain momentum. Pinterest has grown like crazy and proven that many internet users prefer a visual interface to lines and lines of text. The webapp Rummage takes advantage of this by letting you view eBay results in an interface that's nearly identical to Pinterest.
