What if I'm blogging to demonstrate knowledge and thought around professional topics with the intent to help demonstrate to future employers I know what I'm talking about?
I would bet that the potential future employer would be more impressed by your ability to make and solve things, rather than talk about them. So unless you will be applying for a teaching or writing position it would be safer to use your knowledge for starting projects and creating a portfolio.
I'm in product management (though a former engineer). You're right that knowing the tools and how to apply them is definitely meaningful. But I also have to demonstrate that I know more than just the use of tools. And unless I want to build out 20 different projects, I feel like writing about the application rather than just doing the implementation is the best path forward with my limited time
