I use it for anything going from lecture notes, personal notes and plans, letters with university heading, presentations, cv. Some CV examples can be found here: https://github.com/texmacs/tm-forge/tree/main/examples for example this: https://github.com/texmacs/tm-forge/tree/main/examples/kjh-v... some of them can be directly exported to HTML. For myself I use a simpler style and tweaked a bit the bibliography styles to get a list of my publications. I see no reason to use LaTeX to typeset anything which does not require to be sent to a publisher and even in that case I prefer to use TeXmacs for most of the life-cycle of the document and export to LaTeX as I export to PDF or HTML, i.e. for rendering purposes, or transmission. But I guess it depends very much on which kind of document are you thinking to. TeXmacs can be used (more or less out of the box) to create websites. The main TeXmacs page at www.texmacs.org is made with TeXmacs and also the blog at https://texmacs.github.io/notes/docs/overview.html
