My currently biggest issue with SO is that way too many (most?) questions are useless, that is not to say that they are horribly bad and I am even happy to answer them as long as they are unambiguous and clear.
The person asking the question may think otherwise of course but I think most people can see that the group of questions outlined in the title are very rarely helping anyone but the person who asked it.
The down-vote tooltip states the following:
This question does not show any research effort; it is unclear or not useful
If I were to follow that I for one would need to down-vote most of the questions I see, this is neither wanted by the developers nor me. But I take issue with how those questions clutter up SO, it is becomming harder and harder to find the few actually good & useful questions, the ones that more than one person has.
The technologies are not creating a space for new useful questions at the same rate as developers write bad code or are too lazy to thoroughly read the documentation.
Some questions do not even look useless until it turns out that "a semicolon was missing in line 6" or the like. Also people do not bother to abstract, so there are often very concrete cases of a generic problem which also diminishes the value of the question since it becomes siginficantly harder to find and/or estimate whether the question is even revelant. This lack of abstraction also leads to duplicates of course.
Bad question titles may also be on the rise, so unless ((Simple? <Tag> (Problem|Question)) | <tag>+)
is changed to something more meaningful by those who care (or can, as the OP may have trouble forming a coherent English question) those "questions" are also just clutter evem if the content is actually helpful to some.
Now sadly I do not know how to "fix" all this, but maybe it would work to have a system to move such questions into an archive which will have a much lower visibility, so people can still have their specific problems solved and the answerer will still earn reputation and everything but the searches will yield more relevant results.
It seems to me that the format <tag>(:| -)? <actual question>
has become more popular again, I think once a query was done to remove all the tags in \[<tag>\] <actual question>
, maybe that should be done again, could cause more false positives though. Excuses for the pseudo regexes...
