How does SortBridge pick the winner?
Everyone swipes yes or no on the same titles. If exactly one got a yes from everyone, it wins. If several did, everyone ranks those, and an instant-runoff count picks the winner, with a runner-up. Ties left at the end are settled by a coin toss, and the poll says so.
What if we have nothing in common?
You get a second chance. The most liked titles go round again, and each person sees only the ones they said no to, with a line like "2 of 3 liked this. Would you go along with it?" If still nothing is common, the most liked title wins as the closest you got, or whoever made the poll adds more titles.
Who can see how I voted?
Nobody. While swiping, people see only how far each person has got. After swiping, the app shows counts such as "2 of 3 liked this", never who voted for what. Your profile name is shown to the others in the poll; your email address never is.
Who can join a poll?
Anyone who has the link and the app. Treat the link like an unlisted document link: share it with the people you mean to. Whoever made the poll can remove someone.
Does it work for books?
Yes. A poll is for films, TV, or books, one kind at a time, so it works for a film night, a series to start together, or a book club.
