UPDATE: As of 16/3/2012, Game Identification/ITG questions based only on the asker's memory are now prohibited on the site. See the following post:
What are the requirements for asking a game identification question?
It seems to me that the vast majority of ITG questions are asked by brand new users, I daresay people are making accounts specifically to ask these questions. I think personally that this is an excellent way to bring new people to the site.
The problem is with their inexperience with how we do things their questions tend more often than not to be extremely vague and are almost promptly closed every time. I don't think anyone needs me to point out that this (albeit necessary) act likely discourages them from future use of the website.
Now, many community members do attempt to be helpful by directing the asker to our FAQ and suggesting they edit their question to make it less vague, but often the question is closed within 15 minutes of such suggestions. That's not much time to fix it. (Yes they can edit it after it's closed to have it re-opened, but that's not the point of this post)
Should we give these new guys some kind of window to fix their question before we close it, therefore giving them more lee-way to do so, and hopefully keeping a new user while we are at it?
Since I'm the one that brought the idea up, I'll give a suggestion of perhaps 24 hours?
