When posting my questions, I have found that often someone knows the important question to ask. This is at the core of fundamental research and difficult when you are out of your knowledge base to even devise the correct question which would solve the originating concern. It's frequently most important to ask the question. I urge consideration of the author being able to grade or show a value to the question other than just in the response to the question. Also urging here that it go to increase the value of the reputation of the person asking the followup question as it both mentors and helps the original author learn.

A:

The documentation says that comments on SE sites are meant to be temporary:

Comments are temporary "Post-It" notes left on a question or answer.

They can be used to ask for clarification or as a place for necessary discussion about a question.
However, comments are not permanent. All relevant information should eventually be moved to a question or answer, since comments may be deleted at any time for a variety of reasons.
If we introduce a system of rewards for good comments, we would also have to rething the permanence of comments. In my opinion, the presence of useful information in comments
often means that a question or answer is less than complete. I prefer to keep the current system and ensure that we are editing the useful information into the questions and answers.
You can upvote helpful comments. This does not provide a reputation increase, but it lets others know that you found the comment to be helpful
