The site had a great showing due to a kind stranger's post on Hacker News: https://news.ycombinator.com/item?id=36817851
Although the site had 4500 users in the two days following that post, I noticed few people visited the GitHub, which was a giant missed opportunity to gain contributors. So, I added a link to this GitHub repo on the menu of stemformulas.com, and made it easier to contribute by creating a docker-compose setup. If software-oriented people want to contribute to the site, they don't need to download Hugo or Go, just Docker and Git, which many software developers will already have.
Other additions:
- 12 more formulas
- A Python script that normalizes preview images so that they always fit inside the open-graph preview window when shared on social media
