A little inefficiency—not much, just enough to be a speed bump—is a good thing on the HN front page, because it interrupts the usual internet reflexes. Reflexive responses, being predictable, are not interesting. What we want are reflective responses. Reflection is a slower process, requiring a pause. So I think it's good if we readers have to work a little: it slows us down, and maybe activates better circuitry.
I agree with you on slowing down "reflexive responses" but I would say cryptic titles may not be the right approach specially on weekdays.
If I've to read an essay to understand the context the chances are I'll put it off for later and unfortunately will not be able to participate in the discussion.
