Anyone that has content that's interesting to hackers is "the type of person who should be posting on HackerNews". I love this community (and hacking in general) in large part because it's not filled with that sort of elitism; anyone who's able to contribute in a positive way is welcome.
Edit: Or maybe if you're the type of person who can't figure it out, you're not the type of person who should be posting on HackerNews in the first place?
