What are your absolute essential resources?
What content or resource do you never skip?
Blogs, bookmarks, podcasts, tv shows, movies, anything else
Not sure if this is entirely in line with what you’re asking, but I never develop a website without consulting the guidelines and recommendations in WCAG: https://www.w3.org/TR/WCAG21/
Search engines. Be it Google, DDG, Quant, or others, I use them so often I usually have at least one tab open just for that purpose.
