Where to spend my attention?

I wrote in my other blog this morning:

I'm thinking I should work on optimizing my Emacs/Eleventy blog tooling rather than spreading things too thin with things like Drummer.

I'm not sure this is such a great idea. Emacs knowledge is transferable to many other types of tasks. On the other hand, Eleventy knowledge is transferable, well, almost nowhere.

I'm writing this in Tinderbox. I'm pretty good at Tinderbox. It's useful for nearly anything that involves text. Maybe my time should be spent here instead.
