I find it annoying with these articles with generic titles. And then when you dig into them it is about specific products. A better title would be "The Six Levels of Reusability in Vue".

For the HN title, I suppose. The site seems entirely dedicated to Vue, so I'm not sure it'd make a lot of sense to append "in Vue" to all articles. I wonder if it would help them SEO-wise if they did, though.
