Doors or wheels? That is the question: A debate to determine whether there are more wheels or doors in the world has taken the internet by storm. No, really. The discussion has divided social media users into teams, with one side pointing to hotels, apartment buildings and dorms and the other citing suitcases, bicycles and other common items that function with wheels. According to the website Know Your Meme, which tracks popular internet memes, the debate started raging when Twitter user Ryan Nixon posted a poll last week asking: “Do you think there are more doors or wheels in the world?” More than 223,000 people voted in the poll, with wheels beating out doors.
