Stack Overflow has seen a substantial decline in traffic over the last year that appears to be accelerating. https://observablehq.com/@ayhanfuat/the-fall-of-stack-overflow
I vaguely recall the first time I ever asked something on SO, around 2013, the first reply was “this has already been asked before”. No link to said previous question. Taught me to lurk and search more before asking anything there.
I sometimes also suffer a case of “explaining until I figure the question myself”, where the more details I punch into my question, the more likely I am to find the answer myself.
