@delta Onboarding is cool until step 4.
People don't like scanning QRs: when people add my Signal, even if the username is shown on my screen right below a QR code, nobody scanned the QR yet. Everybody just typed the username. Scanning QRs kinda sucks.
And it's rather impractical when the person is not next to me. At which point sending a long link also is meh (or, depending on context, just not possible).

@kbruen Scanning QR codes is a pretty well known UX metaphor these days but indeed not well suited for setting up a chat with a remote person (unless in a video call). We are certainly going to circle back to this UX issue. Meanwhile in reality it's often the case that two people start to chat, then do a group chat, and invite others to join that group which allows to instantly get access to all people in the chat without having to do the qr/link dance with each member.

@kbruen indeed it's generally true probably that a lot of us don't have lots of friends that are also friends with each other. Wherever groups do something together (parent/school councils, sports associations, political groups, all kinds of shared hobby groups) Delta can more easily help, probably.
