In its relatively early days, MO was an organic and dynamic website — it encouraged active discussion among its members, that in almost all cases was extremely fruitful.
But now, even if a similar question was asked over 10 years ago on another forum (typically MSE), a MO question is closed by the MO rules police.
This turns MO into a cemetery of mummified answers instead of an organic place to interchange ideas.
There is no basis for presuming that a similar question asked 10 years ago on another site is not worth re-asking on MO.
I strongly feel that the MO rules police have way too much sway and need to be declawed.
