A widely accepted story about QQ IM is that it allows users to send messages to strangers — The recipient can block the user though. It is believed that it’s hard to monetize a social service for strangers as users as the label itself doesn’t encourage users to stay. Also like QQ, Momo rolled out virtual goods — emoticons, slightly different from virtual avatars QQ began with — and games to monetize the user base. Last year Momo announced 100 million users and claimed it broke even through gaming, and reportedly is planning for an IPO in the U.S. iweju claims it has had more than five million users.
