Pinterest announced a site redesign late today on their blog. While they didn't share a great deal of information about the changes, they did point out that major changes to site navigation and the way pins display were part of the overhaul.
It appears that pins will expand much more than they do now when they are selected. In the redesign, pins will be larger and will have a sidebar that displays other pins from the same boards, as well as, other pins form the same source. This change should encourage more repins and additional traffic to sites with popular pieces of content.
The changes will be rolled out to a small group of Pinterest users over the next few weeks and then will be available to the masses one they "work out the kinks" in the new features.
