Facebook has released a new "authorship" feature that's powered by the Author meta tag. If this sounds remarkably similar to Google's Authorship which was shuttered last year, that's because it is.
With a simple meta tag, writers and publishers can now indicate the author profile or publishing page for any given piece of content. The result is a linked name attached to any shares of that content on Facebook that allows viewers to see the author and potentially follow them.

In my test, it works better on a shared blog post without an image.
