UPDATE: As of November 22, 2011, importing a blog or RSS feed to your personal Facebook account is no longer available. If you want to share your blog posts on Facebook, you can:
- Use Facebook Notes to customize your blog posts in a rich format that’s compatible for readers on Facebook
- Link directly to your blog posts from your status
With a link, the blog post and any thumbnails associated with it will show up on your wall.
You can also use an iframe and embed your blog or a blog you host specifically for WordPress.
This is a pretty cool way to add a mini-site to your Facebook page. Also a great way to add a fangate too to a fan/business page to force likes (though that takes a bit more work, or the use of one of several plugins out there).
But the rss way is definitely the fastest and easiest way to get your blog content on Facebook.
