Pinterest is an electronic bulletin board where users can “pin” images. It is a place to organize and share online images that you find interesting or inspiring from around the web. These images are then categorized into various boards on the users’ profile. Pins are also shared and searchable, which makes Pinterest a wonderful resource for visual information. Well, that's the technical definiation anyway! What it really is a highly addictive new way to find and save interesting ideas--about just about anything you can imagine! Think of Pinterest like Diigo or Delicious but organized visually.
1. Get the Button: To pin on Pinterest, you need the "Pin It" button on your web browser's toolbar. It's so simple to get it. Go to the "About" pulldown menu in the top navigation bar and select "Pin It Button" and then just follow the direction (in a nutshell: drag it to your navigation bar and drop it there).
2. Get Pinning: Whenever you see something you want to save for future reference, such as an image, blog post, video or article, click the "Pin It" button in your tool bar and then select the image to pin. You should also include a brief description of what you are pinning so you know why it's there.
3. Follow and Repin: You'll also want to follow folks who have similar interests. When you do this, you get to see what they are pinning and have the opportunity to repin it (basically add it one of your pin boards). It's a great way to get ideas from others that you might not have been clued into otherwise.
