This app has ridiculously penetration, however. I've met people who use this and no other app not out of the box before. In foreign countries it is easier to get someone to WhatsApp me than it is to get them to text my strange US number.
Sure they solved a pain that's very common, replacing expensive text messaging, but part of their success is how easy it is for users without annoying username/password hoops to step through. They should fix the security, although I don't do anything important over it anyway, but I can't say they went wrong by avoiding a classic username/password setup that might have been more secure from the start.
