Thanks for honoring my critical remarks

I could have easily caused offense and truly would not want to.
Really, any articles about gardening need to be a jumping off point and folks need to try things and observe. As you did with the grounds getting crusty. It seems obvious to me, but might not to a new gardener, that I'd notice that and correct it.
I still think, if one is running their hot grounds to the compost before drinking that first mug, one really needs to take a chill pill

Hey, warm grounds could be GOOD in winter compost!
