Sw Eden has try the application “WordPress” before, but it does not work on my Facebook profile. http://www.facebook.com/#/apps/application.php?id=2373049596 is application for WordPress. What Sw Eden likes on this application is, Sw Eden can know the current visitor of my WordPress blog. But to show the the link as an section on your profile. You must use the Mirror Blog Application. After you add your site, you have to click “Add the Profile”. After it shows in your profile, you can move it to the head-bar, too.
Another way to do is, sign up for the application by yourself and add it to your page.
