Hey Edward, just wanted to add that users who enable their free TypePad Micro blog also have the ability to connect and notify their Facebook and Twitter accounts when they reblog a post. Thus, users who reblog a post can also 'share' that reblogged post to Facebook and Twitter, allowing readers to share beyond their TypePad blog.

Sure, it sounds confusing, but this is why TypePad's relatively-new social-sharing stuff is awesome!
