For the people mout there still using Facebook for anything other than logging into Instagram, talking to parents, or marketplace, the official MLP Page has popped up a quesiton asking "Who is your queen?" with the four mares of G5 as options. I don't know if they plan to expand on this with anything else if there is enough feedback, or they plan to ditch it once the whole Queens Jubilee thing ends, but maybe you can force your favorite on them or something with enough comments?
You can find it over here.
