Thanks for linking to our website (http://www.upsidedowntext.com/)! We're constantly improving our site, and we recently added an option to post upside down text direct to Facebook. Since this post is about "Facebook" tricks we though it might be relevant to your visitors. When you enter text on our site, the upside down equivalent is displayed. Of course, as your post describes, you could copy and paste this text into your Facebook status. But with the new direct post option, you can just click the Facebook icon right above the upside down text on our website, and the upside down text will be sent directly to your Facebook status. This way there is no need to copy + paste. This is an option that the other website you listed for flipping text does not have.
