I have experimented 5-6 various clients, all have features I love: aesthetic, functional, some with unique features like zap support built in, but there needs to be MUCH more development to draw the next wave of adoption. 

The existing features are enough for me, as I’m simple and like interacting with real people w/out language barriers, but beyond me, the existing landscape has attracted and plateaued users, and meaningful growth doesn’t appear sustainable.
