[[https://colah.github.io/][colah's blog]] has a cool feature that
allows you to comment on any paragraph of a blog post. Here's an
[[https://colah.github.io/posts/2015-08-Understanding-LSTMs/][example]].
If it is doable on a static site hosted on Github pages, I suppose it
shouldn't be too hard to implement. This also seems to work more
seamlessly than [[https://fermatslibrary.com/][Fermat's Library]],
because the latter has to embed pdfs in webpages. Now fantasy time:
imagine that one day arXiv shows html versions of papers (through author
uploading or conversion from TeX) with this feature.
