As I have requested before, a feature that automatically quotes the subject of the OP would be a preferable default than the one that currently exists. It is way too easy for users to make their own subject heading that others will mindlessly quote, thus hijacking the subject heading and distracting from and confusing the subject of the topic. Can we please finally get this fixed by making a subject heading automatically mirror the op? Again, I don't mean remove the ability to edit it, I mean by default it copies the OP heading. This flaw is too often abused.
EDIT: I am really not sure exactly what is so hard to understand about this concept. I am not suggesting locking the subject heading or preventing people from editing it if they so choose. All I am suggesting, is that when people reply, instead of quoting the subject heading of what they reply to, it quotes the subject heading of the original post, which then if they so choose they can edit anyway. This filters out the ability for people to essentially abuse people's lackadaisical approach to the subject heading and prevents it from being hijacked, and everyone still gets to post whatever they like.
