Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I came across the "Fantasy Land Specification", it somewhat conflicts with my own simplistic understanding of monads and functors. Is this specification valid, and should I honor it?
I think of this as the "semigroupoid" factoring. Here's the canonical Haskell library, with an explanation of why the extra classes exist: https://hackage.haskell.org/package/semigroupoids. In this library, fantasyland's Chain is called Bind.
