I'd thought it seemed maybe interesting, but the fact it was based on email hit off some assumption I had, this idea that the email infrastructure can't provide security and privacy.

It can, they've done it. Update your assumptions

And they've done loads of other things really well - the onboarding is ridiculously easy, I was told to pick a name and an avatar, picked one of each, was waiting for more screens and such like, but... no, we were done, you're in, that's you.

Multiple profiles are baked in, and given great care. You just click to make a new one, pick a name, and it's done. All transparent and obvious.

Etc etc. Just so much care gone into it, I could keep rambling, I haven't hit a single snag. I clicked on the help menu from inside the app, and tons of really nice documentation pops up. Joy.

Oh last one, the desktop client is so light! Running the .deb here, and it snaps into life. I run old machines, and the Signal desktop app hits the system hard, while this is much quicker. My CPU is breathing a sigh of relief. (Just checked as this got me curious... They're both Electron. So I don't know why DC is so much snappier. Hmm. DC is working on a Tauri desktop client, too!)

Trying to convince non-techies in your life to move to #Signal because it's relatively easy to set up, while mumbling quietly to yourself about centralised servers and metadata and that time they added a cryptocurrency, might soon be a thing of the past.
