As an aside, I originally used GitHut data for Languish. I do my own queries these days, but my queries for GitHub data are still originally based on GitHut queries. And maybe there are only so many ways to query the GitHub data, but it's still nice to have examples to work from.

My current GitHub queries are substantially modified, though, at least in how I get current repo language, because the BigQuery data was very stale. So I use the GraphQL API on GitHub directly these days for that. Though I still get events from BigQuery.
