TECH CRUNCH - Sep 22 - Tinder is launching a new application for social polling. It is called "Tinder Stacks". The new feature will allow users to swipe right or left on anything they want – whether that's polling their friends which photo should be their new profile picture or what outfit should they wear tonight. While Tinder Stacks is discoverable though Apple's iMessage App Store, it's not technically a standalone app. Instead, the new app is included with the flagship Tinder app.
