I discovered it couple of weeks ago and it quickly because a site that I open every day.
Here you can PIN items, photos, anything you find anywhere on the internet. You create boards for your pins. I use it mostly for creating collections of things I am interested in, beautiful places, artwork, products I would like to buy in the future. Here also you can connect to other people by following their boards, repinning interesting things you find there and commenting on their pins.
