Discovery and collection are what Pinterest is all about, and the Place Pins feature that the company introduced a couple of years ago is supposed to take those two things and apply them to the travel market. With the feature, users are able to take Pinterest’s unparalleled visual discovery ability and apply it to travel planning, and it ended up being so popular that the company has decided to expand it significantly. Earlier this week, Pinterest started adding information to billions of pins, ranging from business details to directions, in an effort to make Place Pins more useful, and that’s just the first step in what’s going to be a significant push into the travel market for the company.
