Stop mentioning major concerns in title

Question

On the Ask a Question page, users are currently faced with this:

state the purpose of your code, and mention any major concerns.

I have recently started commenting on many questions with this comment:

As we all want to make our code more efficient or improve it in one way or another, try to write a title that summarizes what your code does, not what you want to get out of a review.

I suggest removing the "mention any major concerns" from that hint (possibly replacing it with something else) as I believe we want to prevent question titles to be more unique and not in the form of:

• "How can this code be improved?"
• "Is this PHP code safe from SQL injection?"
• "Does this title contain the word 'this'?"

All questions on Code Review are about this code, we should consider banning 'this' from question titles.

My suggestion:

1. Remove the 'mention any major concerns' from the title hint
2. Consider banning the word 'this' from question titles

Answer 1

It seemed like a good idea at the time (Prompt for more meaningful question titles). However, it seems like either

1. People have a hard time trying to satisfy both requirements, and/or
2. Some people just won't read instructions no matter what.

I propose that we try a new prompt:

State the task that your code accomplishes. Make your title distinctive.

Answer 2

I like the first idea about changing the hint (I don't think you can sum the concerns in the title - it will usually get longer), but not the one to prohibit this, because this is a keyword in C++.

I believe that the intent of the hint was to make the author write important things first. This seems to be crucial part when writing anything on StackExchange. Many people are just scanning and won't even read the rest, or worse, would write an answer without trully reading the whole question (or simply downvote for not finding the clue in first few lines or what attracts the eye).

Some automatic popup-hint could be used instead of strictly prohibiting this or any title that does not qualify for good title, but I really don't know how to code that.
