But that's the thing, if you're not in this field, it's very hard to tell someone why they should care. You can be all excited that you just had a back-and-forth on here with Paul Graham, tell your friend, and your friend is probably not going to have a clue who you are talking about.
And TBH that's a good thing. HN is a niche community that will never appeal to many people, but we love it because to the folks that it does appeal to, its a truly magical place on the internet.
Not all newcomers want to use HN as intended, but not all oldtimers do either. Discriminating in favor of the latter would be a grand way to shoot this place in the foot, if not the head. As my son used to say when he was 2: that what we not do.
