from news.cnet.com: Facebook made Snapchat, maker of an app for exchanging ephemeral messages, an offer of lasting value: $3 billion in cash, according to The Wall Street Journal. Snapchat, true to its form, discarded the deal just as it does the 350 million messages it handles every day. The rebuffed offer, more than three times the value of Facebook’s successful bid for Instagram, comes as 2-year-old Snapchat explores a massive funding round at around a $4 billion valuation.
