Do you remember having a bulletin board? It was a great way to post photos, reminders and mementos. But, unless someone was in the room with you, you couldn’t share your interests with your friends. Now you can, thanks to Pinterest, a virtual pinboard to organize and share the things you love.

Users must request an invitation to Pinterest, which usually takes a few days. Once you have a Pinterest account, you can create your own pinboards and repin from others. You download a toolbar that can be used to pin items from any website. The photo and information then appear on your Pinterest board, and users who follow you can see your collection of photos and even re-pin them if they like them.

The best part is that you can have multiple boards. One of my friends has a board that she uses to track books she wants to read. It’s helpful because others will share what they thought of the book. You can save your favorite recipes or restaurants. You can plan a wedding or restore your home.

At my company we’re using it as an interactive scrapbook to visually depict our mission. You may want to use it to share products. It’s also great for driving traffic to your blog.

Although Pinterest has been around for a year or two, it has become the social media network to watch after growing more than 4,000 percent in the last six months. It now ranks behind Facebook and Tumblr in terms of engagement.

What will you pin?
