Gah! I really wish the HN submission feature could borrow some ideas from Stack Overflow's duplicate question detection.
(FWIW, the full title is "An Efficiency Comparison of Document Preparation Systems Used in Academic Research and Development", which is too long for HN, so the previous submission also changed it.)
I like how it works now organically. If the discussion was broadly seen, there won't be any up vote interest, and if not, then it clearly hasn't taken its course.
