I think it's interesting because a good title itself is intrinsically "clickbait" or begging you to stop and look for more. From the Paul Graham essay to the header on a high school science fair board, titles are design to get your attention. The problem lies now with content which content created with greater attention to the bait than to the actual body itself. A good designed title is just that, until it lures you into content which does not live up to its billing.
If we can't trust titles what now do we use to decide what content is worth our time?
