As a LW post specifically, I feel like almost all the "classic" OB/LW posts had memorable titles that make it easy to remember what the post is about and serve as a kind of hook/shortcut for that particular concept

I think Alicorn was making a reference to how ads for political candidates in the US now have to include the candidate saying "I'm [so-and-so], and I approve this message." That, or the meme has just caught on. Either way, it may help to know the significance of that phrasing.

(Or it's just a coincidental phrasing, but who care's about that possibility...)

(Previous title was IIRC "I'm Alicorn, and I approve this message.")
