I used Session before switching to WireMin. It’s a good choice for a private messenger, but not an app I would use daily.
I have a personal blog on WireMin, so I can post whatever I want. And I think they made interaction much easier, cuz I can explore public chat rooms and other people’s blogs in the discovery section, which give me more stuff to do on the app.
This is the chat space on WireMin I like to check out daily, people usually talks about privacy news there. i.wiremin.com/invite/?g=k50898835053
