@signalapp I ❤️ #Signal and have persuaded a lot of people into trying it!
One thing though: I notice that the spoiler text formatting isn't recognized by everyone as being ... well ... #spoiler text. The "buzzing" point cloud doesn't invite people to tap on it. I wonder if black text boxes ⬛️⬛️⬛️⬛️ would better convey that text is hidden and can be unhidden by tapping.
Something for the #UX people to think about!
