I am a members in a lot of Stack Exchange sites and in the Electronics there are people casting too many and too easily downvotes which doesn't happen in the rest of the communities! This doesn't help neither the site's quality nor the comradery between us. I am watching questions and there are a lot of people asking, not excellent, but good and on topic ones and they get downvotes, without anyone even commenting on them! This has to stop. No one should cast downvotes on questions or answers so easily. I have found in another SE site a flowchart that demonstrates how should someone think and do before downvoting and as the rules are the same I think that all of us should follow it. It is a great example. What is your opinion on this? Don't you think that something has to be done?
I think you are missing the point of "community review". Each community is different, and you can't impose tight rules about "how someone should think" across all communities.
We all work within the same SE guidelines, but an engineering/science site like EE.SE has very high standards on what constitutes a "good" question. If we're not quick to downvote and close "bad" questions, they would quickly overwhelm the site, obscuring the repository of helpful information that we're trying to build up.
Most of the questions that get downvoted without comment are so obviously in violation of the site policies that it's clear that the user hasn't read the guidelines or even done a basic search for existing information on the topic either within EE.SE specifically or in Google generally. And a lot of these questions come from one-time visitors who never come back to get feedback or to participate further in the site. After a while, it seems pointless to go to the effort of writing a comment; we're just preaching to the choir anyway.
I thought it would be interesting to write a voting statistics for 2014 query and run it against the top 15 sites by questions asked which was enough to cover Tex and EE. Like all data explorer queries this will exclude deleted posts:
Site Upvotes Downvotes % Downvotes (rounded down) Android 18963 7428 28 Apple 59142 8479 12 Ask Ubuntu 239954 43263 15 Cooking 22676 2374 9 Database Administrators 37924 4932 11 Electrical Engineering 72041 11018 13 English 5801 1111 16 Gaming 102122 26889 20 Math 680340 78341 10 Programmers 133274 36991 21 Server Fault 133899 30979 18 Stack Overflow 11670423 1692553 12 Super User 259184 39205 13 Tex 262476 4130 1 Unix and Linux 147922 8918 5 Average 13
So Tex is very much the odd one out and I don't feel that flowchart is representative of how the users of most Stack Exchange sites vote.
That flowchart is just terrible. If I read it correctly, it tells me to leave an outright wrong answer up-voted for days, letting other people think it is correct.
One key difference between EE and e.g. programming is that there are no "compilation errors" in electronics - a circuit will not tell you it's "wrong", it will work anyway, possibly producing sparks and smoke instead of its intended function. If bad answers are not down-voted right away, users may not have the hardware to try good answers on.
