Facebook's Messenger won't just be for chatting with family and friends in the near future. The social network has unveiled a business feature for Messenger that lets you talk to a store about your orders. The option not only spares you from a flurry of email for receipts and shipping, but gives you an easy way to ask questions -- if you want to change your order or add something new, you just open up the existing conversation. In theory, you don't have to go through the hassles of calling or emailing customer service to solve a simple problem. The business effort will only start out with a handful of partners that includes Everlane, Zendesk and Zulily, but a sign-up program suggests that you'll see Messenger used at more online shops before long.
