Love Quarto. I write all my notes, presentations, blog posts, memos, etc in .qmd files. For non-technical stuff I use Obsidian to author (there is an extension which tells Obsidian to treat .qmd as ordinary markdown - ie ignoring the additional Quarto frontmatter and so on), then for everything else I use VS Code with the Quarto extension and just render out to the display format I need. I really appreciate that it’s built on Pandoc and it means I can just use one format and one set of tooling for everything.
