>I think it is really cute that she did this for her boyfriend. She didn't have to do this, but she either likes him so much, or likes the product so much, that she wanted to help him make it successful.

I don't care how cute it is. If you want cuteness, go to /r/aww, not HN. I want meaningful, thought-provoking content.

>I don't see how there is anything wrong with that, and if it is on the front page, then others must agree as well.

Using your logic, we can conclude that there is nothing wrong with majority of content on Reddit. After all, people upvoted it, so there is nothing wrong with it! So far, the readers on HN have been more thoughtful, and I would hate for the quality of this website to go down.
