I guess that's strictly true in the context of reddit but not really true in the spirit of the behaviour. Samsung wanted to allow people to ask questions which they could then answer: it's only because we're so used to reddit's paradigm -- all comments are visible by default -- that this is unexpected. If you were to use pretty much any other platform, it would be up to the question-solicitor to choose what questions are answered and thus seen -- e.g: on Instagram.
