If the setup screen stays the way it is, this is probably never going to take off. The fact that it's officially coming from Tor devs is important and I'm sure people who already use Tor can use this app relatively easily, but if the point is to get more people to use secure and private messaging apps, asking people to enter their xmpp credentials isn't the way to go. Additionally, adding GTalk, Facebook Chat etc. into the mix is only going to confuse people because they'll assume they're secure just by using this app. But in order to have a secure and private conversation you need people on both ends of the conversation to use a client that supports OTR.

They mentioned Pond and Ricochet in that post and I'm a big fan of both but especially Ricochet. It has no setup, no configuration. Just share your address and talk. That's the way it should be. But it's only available on desktops. These days most people connect to the internet only by using their smartphones and if you only support desktop computers (even if you're x-platform) you're missing out on a lot of people already. The perfect solution would be Signal's encryption combined with Telegram's availability, but unfortunately we're not there yet.

I'll keep my eye on this project and I really do hope it takes off but as of right now, it's not that different from any other secure messaging app you can find on the internet that only tech savvy people can use.
