Daniel and I have discussed recently how astonishing it is that, as a user, you're so much more likely to click a button that is labeled "Like" or "Love" more-so than you are "Favorite." While I'm not aware of any empirical evidence lending itself to back this up I can attest to my own personal experience that I give out "Likes" on Tumblr willy-nilly and I'm incredibly thoughtful about giving out "Favorites" on Flickr but they do the same thing!

Has anyone else experienced this phenomena? Am I alone in thinking that the wording of your button makes a huge difference in user participation?
