It is like a giant scrap book you can stroll round the internet looking at pretty stuff and anything that takes your eye you can pin to your board. It is great for recipe ideas, places to visit, clothes and bags you can never afford, make up styles etc if you can imagine it someone will have it pinned. You can also spend hours browsing other peoples boards looking for inspiration etc. I love it but be warned once you have worked it out it is very addictive.
