Pinterest is like that person in high school that everyone wanted to be. Pinterest is good-looking, popular, and it’s the center of attention online. Lately, I can’t help but notice that Pinterest is inspiring more than just the casual afternoon DIY craft project. The unique format of Pinterest’s user interface is making its way into the web redesigns of many other major online companies. A glance at a number of recent updates to websites including eBay, AOL, Stumble Upon, and even Facebook reveals that the simple, visual grid layout is this year’s most popular web trend.
