Should we reduce the vote threshold for closing questions?

I'm all in favor of option 3: ask SE to lower the threshold for closing questions from 5 to 3 votes. (Importantly, the same should apply to the threshold for reopening a question. This is also the ...

Why do people downvote old questions and answers?

When a person in 2017 is looking at an answer that may have been written in 2010 (say), it's not that person's responsibility to try to figure out if the answer might have been correct at some time ...

Do answers with equations and formulas in them get more votes?

In short: I think that the bottom-line is that in terms of correlations, there is not a clear effect. It differs per user, and if we would scale the number of equations by the size of the post then ...

Why do gibberish answers get any upvotes?

As far, as I can verify, it was me who made the upvote. Out of fun and out of curiosity. I also thought it was inconsequential since the answer will get flagged and removed soon and since I would ...

I get surges of upvotes, and they are lumpy in time. Is this because the site is surfacing my questions all at once, or do I have a stalker/superfan?

I can answer this from the perspective of someone who has given clumps of up-votes to users at various points in time, often for old obscure answers. As Tim correctly points out in his answer, this ...

My upvoting policy

I have been using a similar policy since our site was in beta. (I might have stricter minimum quality standards, though ;-), because we are mature enough that many new questions can be answered with ...

3-vote close - how's it going?

I've long thought we ought to close questions faster and grumbled that the burden on the small number of active, high-rep users with close-vote privileges was too high. I'd also support some other ...

How can we discourage downvoting when inappropriate?

I have only a little to add to @NickCox's answer. Down-votes do tend to be sticky, which is a pity when the down-voted poster makes the effort to improve their post. I don't see any reason to suppose ...

I get surges of upvotes, and they are lumpy in time. Is this because the site is surfacing my questions all at once, or do I have a stalker/superfan?

My best guess: someone found your answer that s/he liked, up-voted it, clicked your profile and found other answers s/he liked. There is no algorithm that bounces questions in clusters. What is ...

How can we discourage downvoting when inappropriate?

EDIT: Here is a summary added also in reaction to various comments (some now deleted). Downvoting is not constructive (and not intended to be). It should, mostly, express a view that a post is not ...

Low profile low quality answers

I'll frame this more widely in these terms: people here may readily disagree with (a) someone else's upvote or (b) the OP's acceptance of an answer. Clearing (b) out of the way: An OP's acceptance ...

Why do people downvote old questions and answers?

Votes on this site are highly noisy and so over-analyzing one-offs like this is a waste of energy in my opinion (especially because the criteria for what deserves an up/downvote are completely ...

Community moderating vs systemic attacks

To clarify: programming questions are not automatically off-topic here. Instead, they are off-topic if they don't need "statistical expertise to understand or answer"; as we see under Programming in ...

Is there a way to protect against unreasonable downvoting

For reasons I hope are obvious, (1) these "simple checks, heuristics or algorithms" are in place and (2) their details--even their nature--are not publicized. When you think you have been a victim of ...

Correlation between upvotes and effort

I'd agree that there is at best a weak positive correlation. But what is effort? It's not just the effort that went into an individual answer. The effort of following the forum over a few years ...

Correlation between upvotes and effort

I think there are several (confounding) factors here. The biggest, by far, is the number of views a thread gets. If no one views a given thread, there are obviously no opportunities for people to ...

Is it ever too early to upvote or downvote a question?

Voting is an important signal, but for many askers only acts as a signal at all when given before they get an answer they like (because they then don't log in until they have another question). If a ...

How to ask question that makes you famous and highly upvoted?

After actively observing CV for some time I'd say that the recipe for a question to get noticed and highly upvoted is: Make it general rather then narrow, Use a short, meaningful, but "catchy" title, ...
