Think you get a lot of value out of Snapchat's disappearing messages, payments and stories? You're not the only one. Bloomberg sources claim that Alibaba, China's online shopping behemoth, plans to invest $200 million into Snapchat on the assumption that it's worth $15 billion. That doesn't even include separate talks that are reportedly bent on raising another $500 million. It's not certain why Alibaba is so interested in the service, although its stake in smartphones is probably a big clue. The company wants to promote mobile shopping and otherwise get a foothold on your phone, and services like Snapcash would go a long way toward making that happen.
