Tumblr has announced in a blog post that users can now cozy up to Facebook more easily with improved integration. The upgrade includes three new options for blog owners — a "send to Facebook" toggle when posting, and the ability to share likes and replies on the Facebook Timeline. The new options can be enabled in your blog settings, and users that already have a Facebook connection enabled will be automatically prompted. Just be prepared: with over 50 million blogs and counting, you could be seeing a lot more Tumblr in your Facebook.
