Thank you, that's really good to hear.
> not really sure how to use it since nobody I know uses it yet. I'd be ok with some way of people to discover me
Yeah I haven't been sure what to do about that except having people naturally invite other people and connect that way. What are other ways for people to discover each other? I'm reluctant to have people upload contacts, for example.
> I'm pretty sure some will raise questions about the privacy of messages,
Yes, adding at-rest encryption and exploring other options as well is a top priority.
