Oof, bad timing for that name selection. Especially with payment processing.
The invitation method is interesting, but will likely be its limiting factor vs its draw. Regular Jane/Joe wants to share their username, just not their number or email. Not being able to share verbally is tough.
i like the whole concept but it seamed to good to be true and not some type of backdoored honeypot, ill guess ill check it out when enough people reviewed the sourcecode
back when I was using reddit, whenever it would be posted in /r/privacy or /r/privacyguides it would get like 30 or 40 upvotes in a matter of minutes. for a service that came seemingly out of nowhere, it really felt suspicious to me.
So it has a new ID for each tunnel/channel/whatever. As usual, that comes with the downside of discoverability: how do you find all your contacts when installing the app? You always need an out of band transfer of the user ID - be it email, username, or a transient one like this.
I'm not sure how much better that is than existing chat apps that don't have discoverability.
It's more or less truly anonymous chat. Like you meet someone on the street and need to chat with them, but don't want to give them any personally identifiable info.
It's really cool in concert, but good luck getting anyone to use it. Signal is good enough if you're paranoid. TBH Telegram secret chats are just as good for sensitive stuff and way easier to get folks to use.
