Why are posts that users clearly approve of being closed?

One of the most annoying things about stackexchange has always been the borderline fanatic post closing or duplicate marking. Another question in meta was posed some time ago about the added value of this site. Olin pointed out that "This site grew out of frustration with how SE was managing their sites", mostly aiming at the fact that the site was driven by financial intentions that lowered the quality of the site. Or whatever else that he had in mind, it's irrelevant. https://electrical.codidact.com/questions/278821 -> This is a great post in my opinion. From the answers, it seems clear that it is not off-topic. It's an EMI issue, was identified as such and explained. This isn't 'What microwave should I buy?' or something similar, which would be off topic.

The question has a score of +3, so 3 people liked the question, which, taking into account current population of the site is considerable. 2 people answered and gave good answers! Now it is closed. It sits at the top of the list, and other people cannot add more value to the question, because answers are locked. Maybe Andy had something good to add, he usually does. Maybe someone else.

Of course, this is opinion based. But the message I want to get across is to not become like SE, where questions were closed just because the user had the privilege to do so. Community found the question interesting, closing it seems quite uncalled for even if it did not strictly match the on-topic guidelines letter-by-letter.

The current applicable rule from https://electrical.codidact.com/help/topics would be:

Off-topic
...
High-level use of electrical devices.

If your question treats a device like a black box and isn't about its theory of operation or its design tradeoffs, then it's likely off topic.

First of all, this rule is really just a placeholder since there's no community consensus about these rules yet. I think it is a pretty sound rule personally though. But it actually says "design tradeoffs", which would apply in case a microwave oven leaks spurious/out of band emissions.

Or maybe it is not an EMI issue - the microwave might have a right to send out a certain amount of energy as intentional radiator on its designated carrier frequency. Then it's simply the "first device sending gets the band" rule that applies universally on public, license-free bands.

The OP need to provide more details, which in turn might mean that they have to know a bit of electronics - specifically radio spectrum allocation. What frequency is the microwave and WiFi running on respectively? Both of these could be using a lot of completely different frequency bands, depending on 1) brand and 2) which geographic market the device is intended for. If we don't know this, then answers will just be speculation.

What if the WiFi is running on 900MHz but the microwave on 2.4GHz? Then it doesn't make sense, you don't even have a harmonic from 900MHz in the 2.4GHz band, so the only cause would then be random EMI noise or maybe some strange mains voltage problem.

What if both are running on 2.4GHz? Well EMI and radio allocation in 2.4GHz bands is a tricky subject, maybe there's an answerable question. But how do we know? We can't demand that those answering need to do research about which frequency a certain WiFi router or microwave are using. It is the job of the person asking the question to dig up datasheets for the devices.

If the poster is an EE, there's a chance they have access to a spectrum analyser and could simply measure it. If they are a random "interested bystander", they have likely never even seen a spec.

So after consideration I think closing this question was the right call, not so much because it "treats a device like a black box" but because it lacks sufficient detail to answer the question without speculation.


EDIT

Just for the sake of it, I now asked the very same question, though with a bit more insight on radio spectrum allocation: Microwave oven interfering with WiFi on the 2.4GHz band. Just as an experiment, to see if it get clobbered with close votes too or if we can lure out some more detailed answers. In either case, we can compare my new question with the previous one. Is the new one on-topic and if so, what made it on-topic?

The guy who closed it clearly said he would migrate it to a more suitable section once we had it on codidact. So in his mind lack of detail certainly was not the problem. Quote: "when we get a site that covers computer hardware from user's or IT's perspective, this question would fit there very well. " -> No, we can also cover this from EE perspective, which users who answered the question did, and did well.

The original question was indeed from an interested bystander. I don't see those kind of questions as harmful, they provide insight into different areas of EE. Closing these kind of question does not do anything but deter curiosity, especially for newcomers and students.

I'm the OP on the question under discussion here, and (as you suspected, Lundin) I am what you call an "interested bystander" who would have no idea how to find out the frequency of the microwave oven's or WiFi router's emissions. I fail to see why the question off-topic on this site, but perhaps that's a byproduct of my lack of knowledge of electrical engineering. However, based on what you write in this answer, I agree that my question [continued]

msh210‭ wrote over 3 years ago · edited over 3 years ago

[continued] is arguably not detailed enough -- arguably does not contain enough info for people to answer it -- and could be closed for that reason. Borderline, though, as we see from the fact that someone did post an answer based on typical or common frequencies.

@‭Kranulis‭ In that case it was incorrectly closed, I believe. But it could be closed for the lack of detail/too broad.

Lundin‭ wrote over 3 years ago

@‭msh210 If you can dig up the part number at least of the WiFi router and post which country you are in, then the question might be answerable. I don't know enough of microwave ovens to tell if they use different spectrums, I believe most are on 2.4GHz. But WiFi could be 900MHz, 2.4GHz (most common) or higher GHz frequencies.

But please note that the scope of this site is most definitely electrical engineering, which means design of electronics, not use of electronics, or explaining electronics to laymen. The equivalent question on for example the programming site might go like "I have this program MS Word and I notice that it goes slower whenever my anti-virus software is running, why is that?" That's not a programming question.

Lundin‭ wrote over 3 years ago

@msh210 I now asked a more detailed version of your question here https://electrical.codidact.com/questions/278855, just to provoke more debate and maybe get some more detailed answers.

Re: "But please note that the scope of this site is most definitely electrical engineering, which means design of electronics, not use of electronics, or explaining electronics to laymen." Fair enough.
