I use Emacs daily, as I have done for 44 years. I use it for all of my programming, for editing flat-file databases, of which I do a great deal, for making notes, and for some kinds of writing. Even if I use LibreOffice Writer for a piece of writing, I will often draft it in Emacs first, then use LibreOffice Writer to format it. I find text-editing, as opposed to formatting, much more efficient in Emacs.
