There are HTML tags designed (sort of) for the same pre-rendered and the same. For example a pair of em and i, strong and b.
What formatting tags "correctly" apply (where appropriate formatting tags, for example when making topics/comments here, on habré, on StackOverflow, etc.)?
I myself am leaning towards em/strong because they are more, so to speak, semantic. On the other hand, i/b, like, concise.
