Ironically, they insisted at a very narrow definition of the question and answer format and consequently failed at creating a good wiki. There is no way to approach broader topics. It’s always „how do I do x“, and the accepted answer since 2013 is a jquery plugin which is missing a maintainer since 2015.
The rules there just don't encourage updating answers or re-asking things already asked. I've always said, StackOverflow is a great resource if your specific question is "How would I have done this programming thing back in 2010?"
Ironically, I predicted this already back in 2010 (or whenever the site started). I knew from the outset that disallowing duplicates forever was not future-proof, and that the voting mechanism will favor answers posted earlier, not answers that are more correct or up to date.
