Re: Spot on
The phone service provider is probably not a good analogy as they have interoperability; VHS vs Betamax might be closer. One might be technically better, but if all your mates are using the other, you can't swap tapes... The great benefit to me of Facebook Messenger over all the others to run the (non work) stuff I need to do is that there's a critical mass of the people I need to talk to on there, and there's a very low barrier to entry for anyone else joining the fun. If I have to start sending stuff out in WhatsApp, Instagram, Signal, Twitter... as well it just becomes too much to manage.
