The idea is very nicely presented and the reasons justified perfectly. Thanks so much for this, Zulie!
It’s all about readers. The first sentence your readers see is the title, then the subtitle and finally the first sentence of the introduction.
We can think of it as the LOVE theory.
When you see someone for the first time, if she is attractive and have a good personality, you start showing interest in her, similarly the way you click on a compelling title.
Next you learn more about her to see whether she is your type, your age, and maybe your culture, similarly in the way a subtitle does it for us.
You find out she is your type, your age, your culture and want to start that first conversation until everything changes when you find out she is already having a boyfriend and is in relationship with him since 7 years. Now it’s not about you both, 'yourself’ and 'her’, but it’s about 'that wicked dude’ and ‘her’ — mostly HER. Because now it feels like she isn’t connected to you. So you gradually lose interest in her, unless and until you’re a true lover, likewise, you lose the interest in the writing when the first sentence of the introduction puts you off when it’s mostly about the WRITER unless maybe, you’re a true fan of the writer.
