Wire also has a few other nifty tricks up its sleeve, including the ability to share photos, YouTube videos and SoundCloud links in conversations.
As of its first version, Wire does not offer video calling, and it's not easy to determine if messages are sent. Also, because it's so new, you won't get much use out of Wire unless you can convince others to install it.
With all the other communication apps available, I suggest taking a wait-and-see approach to Wire. It needs time to grow a user base and hopefully make its interface more intuitive.
