The not-so-talked-about but killer feature of Matrix is that you can bridge other services into it. I'm currently able to send and receive messages from Hangouts, iMessage, SMS, and Slack all from within Matrix. If I'm working on my laptop I can put my phone in my bag and not even touch it for 8 hours, because there's no need. I have Riot running on my laptop with a full keyboard and access to all my communication platforms.

It's not exactly easy to do (iMessage requires a dedicated Mac, for example), but it's possible. And it works pretty well. Pulling out my phone to tap out an SMS when I have a full keyboard in front of me seems silly at this point. Hopefully the bridging will continue to evolve and become more accessible to the average user, because it's amazing.

This interests me, as a potential user; but it’s only a killer feature if it’s accessible.

I start by looking into Hangouts matters, because I use Hangouts to talk to some of my family, currently only on my phone and not on my laptop; and I see three projects listed in https://matrix.org/docs/projects/try-matrix-now: matrix-appservice-hangouts, mautrix-hangouts, and Hangouts Bridge. https://matrix.org/docs/projects/bridges/#hangouts lists two, matrix-puppet-hangouts and matrix-appservice-hangouts.

Bridge, puppeting bridge, appservice—I have no idea what any of this means. I’m generally hoping for something like an instruction to install a piece of software on my laptop with `curl … | sudo bash` or some unsigned .exe or something. (Are any of these things basically a Matrix server that I could run on localhost, or do they slot into a Matrix server that I’d need to host elsewhere?)

And so I give up. The content formatting of those pages on matrix.org was super-ugly anyway, it’s clearly either not a good product or not for normal people. (This remark may seem harsh, but this is how most will think.)

What do I need to do for all of this to get Hangouts, SMS and Slack working in Matrix? Is Matrix ever going to focus on users and make questions like this easier to answer, or will it remain a niche product that I should not bother with?

This interests me too; just this weekend I tried to set up a matrix homeserver with matrixsms, puppet-hangouts and puppet-facebook integration and I got no single integration working. I did try to get it working in docker containers, but still.. I would be very grateful to learn if anyone has a recent, detailed write-up! (I also planned to integrate with Skype and WhatsApp, but didn't get that far)
