Social media should just do what GameFAQs and the Wii's Everybody Votes Channel did and just have a daily poll or question.
I feel like it "sort of" happens organically with viral discussion-fodder questions that go around, but it'd be cool to have it pinned in the footer or sidebar or something so you don't miss out.
How many "swords pointing at Flynn" things would we be spared if this was a feature? My theory is that a lot of people use social media partially to chime in on these discussion prompts.
