Mark Zuckerberg must be looking to Asia for inspiration for the kind of platform Facebook Messenger could become. Here’s one idea: An integration with popular car-hailing service Uber that would be beneficial to both companies and, presumably, their users. Such a deal could be a first step in Facebook’s goal of turning the Messenger app into more than a communications tool, but also an e-commerce platform modeled in part after Asian competitors WeChat and Line. That’s why Zuckerberg has held preliminary talks with Uber CEO Travis Kalanick about potentially embedding the service into the Facebook Messenger app, according to sources who have been briefed on the discussions. “It’s very conceptual, and nowhere near execution,” said one person with knowledge of the situation. “But it’s a direction that Messenger has to go in.”
