Facebook Blog Networks is a way to display on your Facebook profile which blogs you own, author and read so that others can find interesting blogs. It also means that each blog registered on there has it’s own page where the feed is displayed (once you have enough fans!), and where readers have the opportunity to review and leave comments about the blog as you can see in the screenshot below (click for larger image, select All Sizes and then Original)
If you do add the application on Facebook (or already have it) please add my blog to the list of those you read. It would be nice to see if any Joeyanne Libraryanne readers are on Facebook.
