> They've seen how quickly a social network can dry up and are wisely using their capital to avoid ending up like myspace. ...they're using their capital to buy more users. There is no evidence that those users will remain with WhatsApp. They're not "avoiding ending like myspace", they are simply delaying ending up like MySpace. No messaging product has managed to maintain a dominant position over the past fifteen years - they come, and they go. I don't see how buying WhatsApp diversifies Facebook's portfolio, because WhatsApp competes with Facebook for messaging users. Google buying Nest is a diversifying acquisition, because it brings in talent and expertise that Google doesn't have (hardware design and engineering). The only thing that WhatsApp brings to the table is users, users who use WhatsApp instead of Facebook Messenger.
