BUSTLE.COM - Dec 19 - Dating app Clover sends out various ideas, like "Snowboarding" or "Game of Thrones Night!" and then users respond if they're in or out. With Clover's Mixer idea, it's a group chat that looks like a Meetup RSVP, and is based on mutual interests. Mixers can be used to host offline singles event. Mixers will be available in the beginning of 2016, in the upcoming version 5.0 of the Clover app.
