Blog articles are not competitive, the pie is simply bigger for everyone on the more popular subjects .

If you look at HN, you will see articles about javascript popping up almost every day. They all get tens of thousands of views, they're not competing for readership.

If you're considering a niche subject instead, the article would not get enough upvotes to reach the frontpage, and it wouldn't get any views at all. There might be hundreds of people aware of that topic (and thousands who would be curious enough to read if it were front page) but it doesn't have enough audience to reach a critical mass of upvotes, so it simply doesn't exist.

P.S. The Youtube comparison is misplaced IMO. Writing books (blog articles) is trivial in comparison to making Hollywood videos (Youtube).
