It is taken right from the subtitle of the article, probably as that was a lot more descriptive than "What Good Is Grandma?". It also had to be shortened to fit within the 80 character limit. It was probably not carefully constructed to eradicate the notion of sex differences. Furthermore, the current trend the article refers is a trend where more and more grandparents are raising children, not solely grandmothers, which explains the wording. It's funny how paranoid people get when it comes to political correctness. But you don't need to worry Golemotron, I promise you there's no feminist under your bed.
