Pinterest, the third social network, announced some slight changes to the design of the site and some new features. Pinterest  has been testing the new look since January.

Pinterest still has the big photos in a grid, just a bit bigger now,along the top of the homescreen is a new navigation bar. A new button in the top left, next to the search bar, gives out  a list of categories, including Animals, Art, and Design.

To make users continue to pin and repin items and spend more time,  there are also some changes to the pin pages. When you look at a pin, you will now see other pins from that board without clicking back, other pins from that source, and similar things to the that pin.
