I see the author is replying here so I just wanted to say I enjoyed following the Formality posts on your blog and updates on GitHub and hope there's time for more of that in the future. Wishing you all the best with this project!

As an aside it may be a convenient reference if you laid out the history of Formality/Kind as I think a large portion of your target audience already knew about Formality. The rename gets a little lost in IMHO, at first glance at least.
