Everything in Pollen is written in Racket, so in theory you could do much more advanced stuff inside your documents than with Latex. For example, you could have a ◊tweet{} element that, given an URL, would go and fetch that tweet and embed it inside your document using whatever quoting privimitives your presentation layer (HTML, Markdown, etc) allows you.
You can also use Pollen to write Latex! Before Quad (https://docs.racket-lang.org/quad/), a quick way to get a PDF output of your Pollen document would be to output Latex from Pollen, then use the resulting document to generate your PDF.
