This particular post quickly turned into a very thinly veiled excuse for me to complain about PDFs, then demonstrate a Gemini Pro trick.
In this case I converted to HTML - I've since tried converting a paper to Markdown and sharing in a Gist, which I think worked even better: https://gist.github.com/simonw/46a33d66e069efe5c10b63625fdab... - notes here https://simonwillison.net/2024/Aug/27/distro/
If you replace `gist.github.com/<user>/<id>` -> `https://gist.io/@<user>/<id>`, you get a gist with nice typography.
https://gist.io/@simonw/46a33d66e069efe5c10b63625fdabb4e is the same gist you linked, but nicer to read
