@dalias @kkarhan @rysiek @FediThing @simonboggis I can conccur. I like signal but I will openly say there's improvements to be made.
And I wouldn't be surprised if something else takes it's place at some point.

I mean there's even a fork of their client called Molly that provides more features.
There's session, there's Briar, ...
But I like signal, I hope they improve. The username is a nice step in the right direction.
