I found two elements of the story very interesting, but haven't seen them mentioned here, so here you go!
First, I thought the narrator's intimacy with powerful figures was interesting. The back and forth on MomNet, Calling out the aliens at their first meeting, and eventually becoming an ambassador. It seems that the speaker is very close to the representatives and leaders of earth, but at the same time seems very average. One idea was that the population was such that it does not really require a leading plutocracy. Earth is more like a large neighborhood, making this somewhat post-apocalyptic.
Additionally, I thought the inverted gender roles was interesting, as it was repeated numerous times throughout the story. Female characters in power, references to "househusbands", ect. I thought this was a really interesting aspect of the story, how would a matriarchal society deal with aliens. For me the silliness and relentless positivity is part of the commentary regarding issues of conflict and distrust (or lack thereof, in this case) that is a part of so many alien encounter stories!
