Imagine if the front page were full with these kind of titles. We might as well change the titles to random numbers.
The last post by this guy that I remember, and the second to last one to do well on the frontpage (perhaps explaining the current behavior), was titled "Off". Can you get any more vague?
In that post all he said about anything being off was "The presenting executives seemed a bit off, too."
My prediction is that before long he'll have a post at the top of Hacker News titled "And" where he ends it with "And that's what I think."
