The problem with messengers is if we don't all pick one, we get too splintered, and each one dies. That's literally all the big ones like Discord, Whatsapp, etc. have going for them are being ones that were the first for a specific purpose and became the default. (Whatsapp for normies who have this weird desire to have their online persona directly tied to their RL one, Discord for gamers/nerd hobbyists, etc.)

I love everything I've seen about Matrix so far... except for the lack of activity there.
