Personally, I want to say the gender component actually happened right about here:
>> Her story is trully inspiring! She seems like a really likable person
We have interesting ways and subtext when we talk about people that show our biases. Actually beyond that the entire article isn't anything about asking Katie questions or how she came about her algorithm. It's more about her fast rising popularity. It's an article that says a woman did something without saying that. I'm not judging if that's offensive or merely a reflection on how we relay news given our society.
EDIT: it looks like the title of the article has either changed or SEO causes some to see different titles than others. Regardless my initial comment should still be valid.
