My mom thought it was easier to do video calls, for some reason I don’t understand. It was harder for me to get synchronization working. And I found the hard way, the best is not to use username (which gets stored centrally, and makes synchronization between devices harder). Although the UI is not best in class, is good enough. One can chat with several people by joining people, but there’s a Swarm group feature I’m still waiting for. Emotions and sensations are not measurable, so I can’t really tell why my mom said what she said, :)
