Pinterest has gained huge amount of popularity over the past few years. Unfortunately one of the drawbacks is the lack of ability to share "boards" outside of Pinterest itself. If you're a blogger or site publisher and want to share these kinds of collections of bookmarks and images, Springpad is the way to go in my book.
Below you'll see an example of an embedded Springpad notebook. By doing this, you can share any content you put into the notebook, now or later, with your audience without them having to have a Springpad account. It's a great way to provide organized reference material with a minimum of muss and fuss.
Regardless of what or how many springs you have, this is a great way to create publicly shared content without having your users struggle to locate the information. You can share the notebook in a collaborative mode, allowing others to post and edit the content, and still have the embedded notebook sharing all the contents in a clear visual format. If your reader is a Springpad user, they can follow your notebook or even reshare it for others to find.
This is just one of the many ways to put these notebooks into use. There's lots more where this came from.
