its sorta like an online bulletin board. you create your own boards and pin things to them. you can also add a 'pin it' button to your internet browser tool bar and if you see something interesting, you can pin it. you can also browse other people's boards and follow them. hope that makes sense.
It is basically a place to get ideas for food, crafts, decor, ect... When you find something you like and want to keep you pin it to your board. If you click on the picture it takes you to the site with the recipe, craft or whatever. It is almost like a really great favorites bar.
