Well done! Witty, zippy, a strong emphasis on the value of actual research. Montell addresses many of the topics that make so many cranky these days: all the things that are primarily ascribed to women or girls, of course. A bit of intersectionality, although without losing focus on the core theme. A good overview of linguistics for those who aren't already familiar with the field.
I just read through thirteen pages of definitions and examples on Urban Dictionary, a staggering number seemingly by offended men, which fail to mention Solnit's essay "Men Explain Things To Me", or the first recorded appearance of the word on LiveJournal, and also fail to provide a usable definition or an appropriate example. One entry appeared to conflate "manspaining" with "manspreading". The irony, it burns.
