Today, I read a post of a very frustated man which tried to resolve a problem during a lot of hours without finding the solution. All I had was this:
Eight hours of trying TO GET first and last character (number) FROM String Please help TO find THE solution
Also he pasted a snippet of his code. So I read it and saw that the snippet did not contain even one try to resolve the problem.
The user was a new user, and I don't want to blame him. But this kind of question start to be very frequent (I'm following the Android tag). I understand that everybody can be a bit frustrated and that you can write a badly formatted question one day. But I find it too easy to let this kind of unconstructive question to be answered by some people. I think that the OP will not make any effort in the future to write better questions as he has answers anyway.
We can select a "Very low quality" flag for an answer in the "Review" part, but not for a question. Actually, I don't really understand why.
New feature idea (but not really a feature request as it's just a discussion about it)
Instead of a "Very low quality" flag, we could add a flag "Need edit" or something like this. This way, if a moderator validate the flag, the post will be "not answerable" until the OP make an edit, which should be reviewed to be back to an "answerable" state.
