I certainly didn't think the article was an argument for polyamory. It just seemed to be an article against monogamy, which I found to be interesting. If anything, this would be interesting to someone who had never thought of it before. A way to get their mind thinking outside what society teaches them.
Strangely enough, what got my mind wondering were questions on a dating site. The questions were obviously designed to test your commitment to monogamy, but they took my mind a different direction entirely. I see all the flaws that were pointed out and agree whole-heartedly. I still found it interesting. If only because it seems that perhaps this could be the next hurdle our society accepts. The small-minded are becoming aware.
