Just last week I was fiddling around with a tangentially related idea. I made some modifications locally to my setup so that when browsing a .org file in eww, org-html-export-as-html would render it in the buffer as HTML directly. eww doesn't really support much styling via shr, so I was working on adding some basic css parsing to expand the range of expression for an org-based blog approach.

Many people export their org file based blogs to HTML and then publish them, but my thought would be to skip that and instead provide a path for eww to directly render org files, cutting out my html export stopgap.
