Ask HN: Anyone using Sphinx for non-documentation websites?

In the recent years static site generators have skyrocketed in popularity [1], presumably with GitHub's push of Markdown.

I have worked more with reStructuredText for a while and I'm interested in the usage of Sphinx specifically; it's in 28th place in terms of stars, but that tells me little about types of its usage in the wild. Sphinx Documentation lists a number of "Homepages and other non-documentation sites" [2] (there's also my personal use for lab website including teaching materials [3] not yet listed), and there is a thesis extension [4, 5].

Anyone using Sphinx for non-documentation websites? Homepages, blogs, course teaching, lab notebooks?
