Or does WhatsApp begin to feel the heat from the 1 billion MAU on Telegram?
A bit of both?
I don't have neither WhatsApp nor Instagram nor Deadbook and the only thing I use from that ecosystem is Deadbook's marketplace, through my wife's account (and she only keeps it for marketplace).
I've got nothing against Craigslist but a $1.5 trillion valuation for Craigslists still feels like too much.
