It’s clearly proving to be the most innovative technology when it comes to decentralized communication, in my opinion.
I think it’s just that there are too many options and the communities are so fragmented. I’m trying out simplex but it still feels like beta software. Regardless I’d like to see it succeed so we have a real private alternative that doesn’t rely on big tech or shady government sponsorship.
