Hm, I thought the first meme did that too (it did for me, anyway). I assumed it was to compare how much I liked something -- for instance, if I said I liked "Daemons," it would leave "Daemons" up as a choice and have me vote to see if I liked something else better than "Daemons." Like when the optometrist keeps changing the lenses and says "Is it better this way? OR THIS WAY?" :D

But I don't know. Maybe it's a glitch. I'll take the second meme later and see what it does. ♥
