Last August, Blogger.com has added a new gadget called Following. By following your blog, your readers tell you and the world that they’re a fan of what you post. Your Dashboard now shows you how many followers each of your blogs has. However this feature was restricted to followers having blog with blogger.com.
However your readers come from across the web, from Yahoo, AOL, WordPress, Typepad... not just Blogger. So to remove this restriction, blogger.com announced that they have integrated Blogger Following with Google Friend Connect.
Friend Connect encourages readers to use one account (whether it's a Google account, a Yahoo, AIM or OpenID account) to follow any site - a Blogger blog, a WordPress blog, or any other site that has incorporated Friend Connect. Each site that a follower joins will show up on their Friend Connect profile. Now your blog will benefit from increased exposure as your readers interact with other sites around the web - and their friends see your blog listed as one they've chosen to follow.
Blogs that are using the Following feature have automatically been migrated to Friend Connect, so you don't need to do a thing.
One note for readers who previously followed one or more sites with Blogger Following and joined one or more sites with Friend Connect: you can decide whether or not to show the sites you've joined via Blogger Following and Google Friend Connect in your Blogger profile. By default, "Show blogs I follow in my Blogger profile" option is turned off. If you change your mind, here are instructions for making this list of sites public on your Blogger profile.
