I use wire (wire. com) for daily chatting. I like it but I couldn't find any good communities in wire. In session, or simpleX, there are privacy (and other) groups in which anyone can participate… Can we start a privacy group in wire so we folks can also hang around?
Well, you said it yourself, Wire isn’t much different in that regard, so Signal is pretty much a one for one substitute.
I would like federation for Signal too somehow, in fact I use Matrix on the side, in particular with people I don’t want to share my phone number with, but that doesn’t prevent it from being a very solid option in and of itself
