I want to give an example from pop music here of why choosing the most popular isn’t the way to go but “it all sounds the same to me”, so I can’t.
I’ll add my xmpp address if I can find it but I don’t believe proprietary comms standards should be encouraged. Bad things happen when we blindly follow the easiest path.
I’ve spent many years arguing for worrying about choosing the right standards (interfaces) not products (shiny things) so we don’t get screwed, once dependent on single suppliers (points of failure.) I’ve learned not to expect anyone to listen too.
