I always describe it like this: You know how some people always pull pages out of a magazine to save them for later? This is kinda a place to do that, electronically, and organize them by "pinning" them to different idea boards that you have. For example, I have a board for recipies, hair ideas, clothing ideas, crafts with the kids, holiday crafts, etc. You can make whatever boards you want. You can also follow your friends, to see what they're pinning.
