To use it, you just save the location to a new list and share that with your friends. Your friends will then see their options, overthink the decision, and vote via a thumbs-up or a thumbs-down. They can also add their own suggestions (or remove yours). It's highly unlikely, however, that their recommendations will be as apt, surprising, and chic as yours.
So, get out there and start a poll, then decide to do something else at the last minute anyway.
