I run a multi-author baseball website (powered by WordPress). The website is set up to automatically post all new blog posts to the website's Facebook page (Add link to Facebook plugin) and automatically tweet the post to the website's Twitter account (YOURLS: WordPress to Twitter).
I have also set up automatic posting of my own articles to my personal Facebook profile and Twitter account with ifttt.com.
The next think I am looking for is, how can I automatically "Like" all posts that are not mine on my personal Facebook profile?
