Are you curious to see how your friends are using WordPress? Give the new and improved Friend Finder a try to connect with your Twitter, Facebook, and Google contacts who have WordPress sites! After authorizing WordPress.com to use your Twitter, Facebook, or Google account to find your friends (don’t worry — none of this account information is saved!) you’ll see a list of people you know who have WordPress sites. Click Follow and each time your friend publishes a new post it will show up in your Reader under Blogs I Follow . If you have multiple blogs, make sure to set the Primary Blog in your Settings so the correct blog is shown to friends when they find you. If you’re interested in finding more cool blogs to follow, browse our collection of Recommended Blogs and try adding some topics to follow in your reader using the box in the bottom left.
