Signal won't be able to make even a dent in WhatsApp's empire. WhatsApp isn't just a messaging app. With its stories and statuses, it's a mini social network in and of itself. Beyond the HackerNews crowd, most people don't care about privacy. They care about features. Signal won't be able to compete with WhatsApp unless it builds some of those features into its app. Edit - HackerNews crowd seems to get tunnel visione…
Now WhatsApp is on a similar suicide mission.
