I am running my own home server, everyone in my family has an account they use there (the domain is our last name). Non-techy people use it and like it (past the initial setup, since setting up a custom domain requires a few more clicks than :matrix.org account). I am not waiting for the day, though, when they will need to set up a new device without access to the old one because of E2E setup. I would like Matrix to provide a setting to advise UIs to not use e2e encryption for the same domain -- that's useless if you trust the home server (my family do trust my home server).
> I personally haven't met any "real" people who are even aware of Matrix. When I broached it with a non-IT friend, they were actively uninterested in unifying messaging applications as they had "facebook friends" and "whatsapp friends" and interacted with them differently.
I tried to sell it too with the "unify your messaging apps", but this is a wrong selling point to new users. First they need to start using matrix as their messaging app, realize that it works well, including VoIP and video calls. Once trust is there, only then start thinking about using bridges. Because there will be rough edges (e.g. federated voice/video calls do not work).
Because of the way bridges integrate to third-parties, they are not bug-free. Reliability is just not great yet. Maybe except a hosted service, Beeper[1], which is run by people who know most about these bridges and can provide support.
To sum up, I am using Matrix for my family network, and some bridges personally; I am not yet planning to spread the use of bridges beyond myself. Besides the encryption setup, I like the UI a lot. I also use gomuks[2] from time to time, which is a terminal matrix application. I have not stumped into server-side problems.
I am donating monthly to Tulir[3], the most prolific Matrix bridge developer (and, to my knowledge, co-founder of beeper). Because I started using Matrix thanks to his bridges.
Oh, and I love the Matrix sms bridge[4]. I set it up to see if it works, and I am not going back. It's great.
