While I understand it's a lot of work, and some (most?) might be posting low quality answers, my main problem with stack overflow has been exactly that over time, the top answer becomes stale.
The question is still relevant, but the best practice or library, platform whatever changed... That is a problem the stack overflow model has a hard time adapting too.. and it just gets worst over time..
Original accepted upvoted to +20 answer: "Take Y and drive it into X, grep output for Z and place in AZ for processing with the -kombucha switch"
Answer posted yesterday by "NewUserXX123", a first post: "Take A and drive it into B, grep output for C and place it in DD for processing with the -kombucha switch"
It gets pretty tiring responding with a custom comment and downvoting, only to have "NewUserXX123" then cuss you out in a DM about how you are a total @!#$%()&!@$%.
