I write informal notes to myself in a basic editor like ee/mousepad, things I need to write rapidly for other people in Openoffice, and I have a side hobby typesetting out-of-copyright books in texlive with the Kyle editor, which has a wysiwyg type interface that updates a preview window when I press save, it also has an autocomplete feature for tags. Texlive also comes with pdfjam, for splitting and concatenating pdfs, and pdfbook2 for creating book signatures out of pdfs.What do you use to write letters? To write articles, etc?
I also write formal letters in latex with Kyle.
However, I'm just a hobbyist and no expert on latex.
Texlive does seem very bloated, but they don't update it very often maybe once every 3 or 4 years.
