I'd love to see a graph of the stars over time. Or perhaps a graph of a new-stars-per-month statistic. That would show which ones are getting more popular and which are in decline.
Jekyll has a ton of stars, but that's probably because it's been around so long.
We used to have those charts per site generator on the detail page before the Middleman -> React Static rewrite of the site.
Would love to see them back myself. Pull Request at https://github.com/netlify/staticgen would be super appreciated, since it might take a while before any of the main contributors will have time to add it back in.
