@Jan_B it's solely a mod's responsibility (not necessarily just me). And it's quite a tedious process, and understandably none of the mods want to do it. Other than the PotW picture/sidebar on main, there's basically no support for contests like PotW on SE sites. Additionally, with decreasing site usage/traffic, it has a lot less appeal than it used to.

Do you have a specific example question or context in mind?

@RomeoNinov I don't know what to tell you. How does a community "reevaluate its own criteria"? Voting is anonymous. Communities are a combination of moderation (which is quite hands off here) and developed or organically grown customs, norms, mores, and memes (in the classic sense; not internet "memes"). What would you have the community do, or do differently? And how much ability do you think community has to make those changes, compared to your similar/same question in 2015?

@RomeoNinov If that is your opinion and approach towards writing answers, so be it. That is definitely your choice, and your preference, and that's fine. But if you find yourself consistently at odds with, or not finding as much support from, the community you choose to participate in, at a certain point you have to wonder if the community has different expectations or preferences than you do.

@RomeoNinov I think confirmation bias is heavily in play here. But that's up to you to evaluate.

@RomeoNinov But you're not really comparing similar answers, are you? Your answer is rather lean on information. One of the other answers has a link to a manual; the other answer goes into useful details for the questioner. Stephen's answer, at the minimum, serves as a jumping-off point to find more information, by being fairly information-rich by itself. Yours doesn't provide much to work with.

You asked a similar question in Meta in 2015, when the site was much more active.

@RomeoNinov So someone think my answer is not useful... And nobody think is useful. Hm, this mean there is something wrong with the environment in this site. I mean this as constructively, and as friendly, as possible, but there are other options beside "there is something wrong with the environment in this site." It's egocentric to jump to that specific conclusion, and not also consider "maybe my answer isn't great". At the very least, a single person probably thought your answer isn't great. How do you conclude it's a systemic issue with the site?

@RomeoNinov I don't know the context of the answer you quoted in your Meta question. Without context (seeing the question, perhaps other comments), I don't believe toxicity or poisonous attitude can be inferred, at all. If you're seeing a pattern of downvoting on your, or another user's, Q's & A's, there might be a serial downvoter targeting you specifically. That's something to look into.

Personally, I'm a serial upvoter for most things, unless they're seriously wrong or incorrect.

This is a pretty nebulous question. I think we're going to need some examples for discussion.

Sorry to point you to a (closed) dupe question, but it's the direct question, same comments apply.
