It would be great if we could add our Wickr username to our profiles. Wickr is extremely popular right now and offers great security features. It's also just as easy to use as Skype and has superior perfect forward secrecy to OTR-based messengers (Using AES256 rather than AES128). It supports file and media sharing, self-destructing messages, a contact list, and free-space wiping. It uses end to end encryption and authentication. Just a thought, hope you like!
