       | That's great for the person who asked the question, because

       | 
       | But I'm not there because I'm doing $X. I'm doing something
       | totally different that does actually need $Y.
       | 
       | I've had times where I've found a dozen different SO questions
       | asking about how to do $Y and ever damned answer to every damned
       | one of them was a "you don't need $Y for what you are doing...do
       | this instead" answer.

         | Now that doesn't quite fit for "best practice" questions where

       | Good. As much as I hate that people copy and paste without

         | There are two conflicting purposes going on here: the need for
         | archival, and the need for discussion. Over the course of 10
         | years, its clear that some information should be archived,
         | while other material should be rediscussed and reupped.
         | 
         | I'll plug my "idea" again (just an idea guy, lol). Which is
         | that question/answer sites need to have an "epoch period" of
         | sorts. Back in the 90s, I used to play a browser-based MMO game
         | called Utopia (and its sister game: Earth 2025). Every 6
         | months, the scoreboard would be archived and the game reset.
         | 
         | The idea is: players come and go. You need a time for players
         | to "leave" (ex: retire for a season, or permanently). But you
         | also want to keep connected players together (ex: a kingdom of
         | 20 players may have become friends, so you want to keep those
         | social connections).
         | 
         | Resetting the game from scratch every few months meant that all
         | players were nominally on equal grounds. It also allowed the
         | game to change its rules and rebalance from update to update
         | (maybe some strategies were too strong, or too weak).
         | 
         | Q&A sites would benefit from this. If a question is renewed in
         | a later epoch / season, maybe its truly different than the
         | historical answer from 5 years ago.
         | 
         | ------
         | 
         | StackOverflow also treated its upvotes/downvotes like a game. I
         | am convinced that this causes long-term issues in the
         | community. Resetting these points back from scratch (with maybe
         | historical notes on former points) would go a long way towards
         | determining who is or isn't active and at which times. (Ex:
         | someone may have been highly active from 2014 to 2016, and the
         | archives would indicate it. But that doesn't necessarily mean
         | that they're well-versed in 2020-2021 "season" rules or
         | culture)
