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.

The Shen Programming Language
Shen is a very unique language, and one of the ways in which it is unique is that so much of its marketing, information, etc is non-obvious, and less accessible than you might want.
I think the main thing that I find compelling about shen is its type system, especially its sequent calculus system (for defining types in a way that would not be possible for most languages).
The other thing about it that is compelling is how portable it is. the main language is implemented in a simple kernel language; someone who wanted to port the language to a new environment would need to implement a small (relatively) set of primitives, and then you can run the entire shen environment on top of it.
Its worth looking into, however I do caution that it has plenty of rough edges etc.
For me personally I think of it as an inspiration for programming languages I wish to develop someday. Additionally, if you ever worked in a certain environment and really dislike that the language is a bit weak, shen might be something you could port to that language and use. For example, I recently updated https://github.com/deech/shen-elisp so that some of its rough edges were a bit smoothed down and should be more usable; I haven't actually written any shen yet that runs in emacs. That's still a ways away.

The Shen Programming Language
There are open source ports that have a clear license now: https://github.com/Shen-Language/shen-sources/blob/master/LI...
That said, even if I don't use this a lot, I pay for Shen Professional to support development. Like you, I got and read the book and like the ideas, and I decided to support the project because I rather be sold something explicit (a programming language) than who knows what I get sold through a language that is open source but depends on a few or even one big company to pay the devs.
What are some alternatives?
