I’ve been using Signal for about ten years. In the beginning, it was just my wife and me. Then I added a few Android tech friends. Eventually, I convinced a few more friends to join, but most of them left after a while. Later, I got some family members to try it, though they barely used it.
Over time, I added more tech-savvy friends, then more local friends and family. Eventually, I started connecting with tons of online friends from Bitcoin Twitter and then Nostr. Even the friends and family who had left before came back. Now, Signal has become my main way of communicating with my family, several friend groups, and just about everyone except a few outlier RCS text chats.
My point is: it takes time for people to migrate from one app to another. It can take years before adoption really takes hold. Apps like White Noise and others will have the same journey. Keep using them. Don’t stop. You’re on the right path.
