Yeah, except for when there should be current answers. Most of computing is in constant flux. There's a mountain of 10+ year old answers that simply don't apply any more.

Yes.

They belong on the existing question - unless the existing question is poorly asked and the new one is better asked.

New answers can, by default, be added at any time - and should, if existing answers are actually out of date rather than simply being old. (Many 10+ year old answers really do still apply.)

Asking the question again is not how the site is designed or intended to work.

I answered one question 13 years ago where I still gets points for. Computing as a whole isn't so much in constant flux, it is only JavaScript that changes so much. Hell, I learned to use Apache 30 years ago, and I didn't need to learn anything new the last 25 years of that.

The change to Python 3 effectively either invalidated or deprecated tons of Python questions, or else required new answers to be written. In many cases we ended up with an annoying pair of popular questions to capture major 2->3 differences, because you'd get clueless users who thought they were running a 2.x interpreter but were actually running a 3.x interpreter, and also the other way around.
