Sometimes, I encounter questions with vague titles: they do not always specify what is really being asked.
For example, there is a question called How do I find all the files that were created today in Unix/Linux? which is asking only about files on Linux/Unix. This is clearly a useful question, but I think "How do I find all the files that were created today in Unix/Linux?" would be a more descriptive title.
In a situation such as this one, should I change the title to describe a question's topic more accurately, or should I leave the question's title as-is?
