:::Mike Brown clearly knows that he can't get away with naming a planet (-like thing) after a character from popular culture, which is the main status of Eris the Discordian goddessfrom her appearance in The Illuminati Trilogy.  So the fact that he only points to the Greek origin of the namei.e., the origin that would be seen as legitimate by the IAUis not particularly strong evidence that he didn't have any other origin in mind when he suggested the term.  That Brown would change the name of the moon from Gabrielle to Dysnomia does indicated a somewhat playful nature.

On the other hand, if you were to ask a randomly selected representative of nerd culture who "Eris" was, I think you'd find a lot more people referencing The Illumninati Trilogy than the Trojan War.  This is not to do a mind-reading act and say that we know something about Brown's intentions that he's never mentioned, but to suggest that the Discordian connection is a significant association that deserves a few words in the name section.  It's not just a few freaks trying to piggy-back their freakish belief system into a scientific article.
