Fair enough, my 5, but I would rather delete the OP's post immediately, as not a question.

Thank you.
I think we should try to help (if possible), even if the question isn't good or clear (or even not-a-question!).

Sergey Alexandrovich Kryukov 15-Apr-13 12:20pm

Well, I would agree about "not clear", and sometimes I even do help even when the post is not a question, but I think we are already overwhelmed with non-questions (you many not see all of them because I already removed many), so it's bad to encourage bad behavior. And if posting non-question was a casual mistake or a person is new to the forum, she or he can legitimately re-post it, after reading "sorry, this is not a question" comment. Do you see my point?

I remember I tried to suggest some more complex schema to Chris Maunder, but he convinced me with "just delete it immediately". Not-enough-information posts are even harder. Did you notice that huge percent of inquirers providing not enough information and asked for extra information just abandon the threads? Such ignorance is pretty bad. I try to delete such threads when I occasionally face with them, but they are hard to detect; nobody would like to visit old posts.

Sometimes experts blame inquirers to failure to search this forum for an answer, but frankly, it is overwhelmed with trash.

I see your point. I'm torn between two dispositions: (1) Make the Question useful as reference. (2) Just being helpful.
Point (2) prevents me from deleting questions.

I have a final comment which may alleviate the burden of #2 (:-): a person who was unable to formulate a post as a question when a forum is called "Quick Questions & Answers" and feel too offended to put a better post later, in response to the "Sorry, not a question comment" might be a pretty hopeless target to help.

I would prefer to dedicate more time to a user who really deserve help. By answering bad "questions", we sometime do it at the expense of mode promising members. How about that? You probably note that sometimes I'm not afraid of spending my time for answering a question in detail when I hope that the inquirer can really use it. Why? By saving some time on bad inquirers. It all has its back flip of a coin...

While I might be tempted, I prefer to not discard anyone. However, I think it is just personal aptitude.

Sergey Alexandrovich Kryukov 15-Apr-13 16:32pm

Please see below, in reply to your other mention of "tempting"...
Good discussion anyway, thank you.

would you give me something more simple please?

CPallini 15-Apr-13 15:10pm

Well, it is already simple.

Sergey Alexandrovich Kryukov 15-Apr-13 16:03pm

Great answer! another 5! :-)

CPallini 15-Apr-13 16:17pm

You're tempting me... :-)

Sergey Alexandrovich Kryukov 15-Apr-13 16:30pm

Tempting to what?
To remove some of the non-questions? :-)

(I refer to our recent discussion. In many cases, we really should pay attention for the character of the question. The non-question can be in the middle between brainless spam and "almost a question". Depending on how it's like, we can judge on how reasonable could be a decision to answer...)
