Seriously, I think this has gotten out of hand.
Titles should clearly inform the user what the question is. Simply titling your question as "Ooh, spooky riddle", or "Riddle, Part 2", or "Riddle, the Sequel" or "user_name's riddle part 2", or "A crazy riddle", or "A very tricky riddle", or "This is a hard riddle", etc etc.
See where I'm going? The questions list is literally populated with these horrible titles. As a community we need to have unified support and figure out how to appropriately title riddle questions. Because the way it stands, with the current non unified naming conventions, at first glance nearly all riddle questions sound the same.
Furthermore, do we even need this stupid "part 1, part 2, part 3" naming convention? Questions should be unique on their own, and only if the question itself is actually related to the question before (and not just "they are both riddles, so they are related").
My proposal is to title your riddle with the first line of the riddle., followed by a "..." to imply it continues. This way riddle titles will not be misleading and can actually give user's a glimpse of what the title is.
