Well I use it as an online bulletin board. When I see something online that I like I "pin" a link to a board on my page. Then I don't have to print it out or try to remember it. When you go to the home page and aren't signed it you will see the most popular pins. When you are signed in you will see things pinned by people you follow. Like I have a friend who makes jewelry and I follow her so when she pins something it will show up on that front page for me. If you choose to follow people who like things you like somtimes they find stuff you wouldn't have seen on your own. I don't usually repin, I try to follow the link back to the original post and pin from that. Does that make sense.
