# blogdown

> **Henrik Bengtsson** (@henrikbengtsson; 16/6): #RStats wish: a near-zero-friction way for the reader of a {pkgdown}, {bookdown}, {blogdown}, Quarto, … to report on typos, grammars, etc. Something like a light-weight in-page commenting framework which only takes a click or two to submit. Ideally, no signing required  [&#8618;](https://twitter.com/henrikbengtsson/status/1597701166334627842)

> **Jason Mercer, PhD** (@ecojydrology; 1/0): @tcarpenter216 I like to turn projects into websites via quarto and gitlab/hub. It's how I mix code and narrative so I remember what I was thinking when I wrote the code. If I don't want to share my narrative I can use knitr::purl to strip the qmd files into plain r scripts (e.g., for a paper).  [&#8618;](https://twitter.com/ecojydrology/status/1597767726222561280)
