I am amazed by how many chats are coming out. I wonder what's the difference between Bleep and Telegram, are they all adding value or are they trying to differentiate small niches of the market? Also, with all these free services I'm always worried about the longevity of the service. Whatsapp has a proven record of being sustainable, so it should stay up even with not so many users. The free alternatives need money, so they will either use advertising, form of premium content, external investors, or in the end, shut down.
