I don’t entirely agree that more and better documentation removes bugs, problems, questions, concerns, or cuts too much into a 50% drop in site usage. Having documentation is just another tool in the toolbelt, to be used alongside community forums.
Discovery process for myself and many of my coworkers has always been; Look up obscure errors, problems, etc. to get an idea of what I’m dealing with, and then off to the documentation.
Can confirm, I have mangled UIs in almost every CSS framework, its a talent of mine apparently ᕕ( ᐛ )ᕗ
