Maybe you're walking to get coffee in a few and it would be awesome if 5 people came with you, or midnight game of soccer would be perfect. Crowds is an app for starting crowds. Post one, and your followers rush to join in if they're interested. You can make your crowd private too, so that members must be quickly approved before they get the address or meeting spot etc
