We took our time to remove this niggle, but you should like this little update:
If you click the "reply" button on a comment containing a headline your "Title field" is now pre-populated with "Re: (same headline)"
You can if you like change this to insert your own headline or - if you are perverse, depopulate the field entirely .
Of course, If you reply to a post without a title, you still get an empty/optional title. But enough of this madness...
