i am often shocked at the lack of photos and diagrams, particularly in technical blog posts -- if you'll indulge me in a related tangent. the word-only approach likely points to the wide spectrum human cognition, and maybe some entrenchment around the arbitrary masculinization of backend vs "pretty frontend/design", and "technical" vs communication/marketing.

EDIT: I recognize this article is from NYTimes -- that need not be our gold standard for inspiring awesome communication!
