I am. Seems nice and cool but not many people are there yet, plus the app has a lot of way to go. But I believe it can accomplish something interesting
I think there is always someone who is more willing to try it, so you start from them. Like a a techy friend or a parent who doesn't really care as long as they talk to their child. Then you can proceed by complaining to your social circle about the bad quality of the apps you currently use (like messenger). Someone will be convinced eventually. I recommend you go with signal though since element (x) apps are still not ready for commercial every day use.
Maybe on v134
