When reviewing close votes, I regularly encounter questions with the following history:
- New users ask a question which is unclear because it is lacking relevant information.
- People add comments, asking for the missing information.
- The OP adds one or multiple comments, so that it in the end becomes clear what she wanted.
- The question gets answered.
Now the problem is that the question as such is still unclear - IMHO reading the comments should not be required to understand the question. I obviously have the option to edit the question myself, or add a moderation comment. This works to a certain extend, but it would be better if the system helped to guide new users in this situation.
So, when a new users clicks on "add comment" on their own post, the system should show a notification informing about the option to edit their own post instead.
