It doesn't really matter if people click anything. If they can send a like via a command line API, then that works. It's artificial to be sure, but the man point is the dispel the myth that the people and interaction are on twitter and facebook, which I think has been with some vigor, since twitter got zero likes (and zero shares and comments for people that want to count those instead). I'm not quite ready to give final counts since I am still getting comments and likes here and on facebook, but soon I should have some numbers from the experiment.
