What's wrong with Kik.
or skype, telegram, whatsapp, snapchat, messenger (if you mind zuckerberg looking at your stuff), google hangouts, tox, and the other plethora of messaging apps out there.
i've standardized on steam, facebook, skype, and snapchat. easy enough, don't have other people to talk to on those other services.
OTHER THAN THAT i still feel that this isn't that bad of a service, just really have no use for it.
