The guy who wrote the article is giving a talk with his partner this Tuesday at my local poly organization, OpenLoveNY. I posted the announcement on the regional forum. Unfortunately, I can't go this Tuesday. This is the first Discussion I really wanted to attend, too! Waaaa.
His talk is called, "There's No Such Thing as Polyamory," and will be based on the article this excerpt comes from.
