I'm not suggesting to apply this on main sites (-3 score), as wrong answers or with bad advice/bad code (etc) are beneficial being less visible (greyed out).
However, Metas are different beasts to their main sites, and there's some leniency towards Meta answers.
Meta Answers:
- Don't need to strictly answer the question
- Are often discussion points, adding alternative or additional suggestions or ideas
- Are often not "right or wrong", they're opinions, and votes on them are just X people agree or disagree
So on Meta sites (maybe not all of them), the answers with a negative score being greyed is not necessarily a good thing, as they're still potentially viable discussion points, showing what people think.
Example:
https://meta.stackoverflow.com/a/288232/2632129
I'm happy to leave it as the question is about usage of a specific tag, and the downvotes show a general consensus that people disagree with a certain side of the argument. However, it's almost pointless me doing so when it's barely visible.
We can see it's (currently) -8 and most people "disagree", and it's at the bottom of all other answers.
An example showing we're losing visibility on a good discussion point:
Can you bring the color back to meta?
While that answer has a -38 score it also has +44 votes - on Meta specifically I don't think it's logical/useful having that answer less visible.
There may be some Meta sites where this wouldn't be preferred - but on MSO and MSE (at least) I think it would be worthwhile.
Do you think it would be welcomed to not grey out -8 negatively voted answers on at least some Meta sites, to allow them to be seen as part of the discussions?
