Just a thought, but it might be possible to create a tumblr or tegaki diary clone in twtxt format. Illustrators upload their work to twitter and pixiv, but I think self-hosting has various advantages.
@hashrock@twtxt.net yes that is exactly my idea with pixelblog, and I’m up for working together on improving it or making it part of yarnd
one option is to make an extension for a CMS like yellow which i been using for years and I already talked with the devs about twtxt
@prologic@twtxt.net it could look like the gallery/grid view on http://darch.dk/pixelblog and work in a similar way where each thumbnail links back to the post containing it
@hashrock@twtxt.net you can already point pixelblog to an external twtxt.txt, but generating thumbnails does only work for local files.
And for mockup take a look at: https://darch.dk/pixelblog/gallery/
But it would be nice to have a more tumblr look with thumbnails in their propper aspect ration as in your mockup above.
