The new buttons include the Vulcan Salute, Captain Kirk (Haha), Spock(Wow), Geordi La Forge ((Sad), and a Klingon (Angry). The buttons are available for “some Star Trek fans in the U.S. and Canada,” according to Facebook reps. In order for it to change for you, you must Like the official Star Trek Facebook page.
Facebook experimented with their Like buttons earlier this year, as they added a flower button in honor of Mother’s Day. No word yet as to how long these buttons will be available.
