Some people say that Pinterest is the new Google. People head to Pinterest to search for project ideas, recipes, and news about their favorite topics. Using the Follow Interest tool, you can easily find new pins about your favorite topics without following other pinners one at a time. Pinterest will find the most popular pins from all of of the users who are posting about the topics you love and display them in your Pinterest feed. I've used this feature to find new pinners to follow and find more great pins about my favorite topics: health & fitness, technology, and DIY.
