I absolutely LOVE Pinterest. I have always needed a place to store the ideas and tutorials and patterns that I find on the Internet. I have tried printing them off and putting them in notebooks, setting up an elaborate folder system in Windows Explorer, making each a favorite in Internet Explorer among many other things. When I found Pinterest, it was just what I needed.
You can set up boards (folders) for anything that you want to pin (ie. save the internet address that you want to go back to.)
