What purpose does the typesetting tag serve?
Typesetting is the retrieval of the stored letters (called sorts in mechanical systems and glyphs in digital systems) and the ordering of them according to a language's orthography for visual display.
Hence it is what TeX does internally, though I think the process of writing a TeX file is usually also called typesetting. Reading through the list of questions tagged typesetting I see several questions that should be tagged typography, some where typesetting is entirely superfluous and some where it is applied as a catch-all tag.
Should typesetting be removed?
