You're joking, right? A sizeable number of people here on HN read the comments before reading the item, partly because the comments often have more information than the item, and partly because the title is often less of a guide to the quality than the comments. I always check the comments first, not least, in addition to the above, they usually load faster.

Many people read the HN comments before the submission, and the spoiler, well, spoilt it.
