Same. For me it was basically that as a body of knowledge, it kind of stabilized. I didn't work in a rapidly developing field like the newest JS frameworks, so for what I knew, most stuff simply became answered.

Whenever I took the time to make a long answer on a question, I saw some mod close the question as a duplicate of an existing one - even though the question could have some minute detail that was different, or perhaps there was some recent change in the landscape that meant an answer in 2020 would be different from one in 2013. But no: aggressive marking as duplicate even though clearly as a _community_ it would be much better to have a more recent discussion, perhaps more alternative answers and just allowing the near-duplicates.
