One of a few Big Love-associated pieces, this in the Chicago Tribune late last week:

NEW YORK –
John and Sue have an offbeat marital arrangement. For the last five years of their marriage, Sue has spent three nights a week with her boyfriend, Fred.
And that’s not even the strange part.
As it turns out, John openly shares Sue — and their king-size marital bed — with Fred. Confused? Consider this: During the rest of the week, Fred sleeps at home with his wife, Peggy, and their male lover, Bill.
John, a 71-year-old San Francisco-based researcher, also has relationships outside his marriage to Sue. He has three current girlfriends, Fred has two and John’s wife has four boyfriends. He even refers to Sylvia, the sister of one of his wife’s lovers, as “my sister in love.” Following along?
While John has nothing against monogamy, he said, “You have to spend a lot of energy to be monogamous.”
It’s hard to imagine a more energetic bunch than John, Sue and their various lovers, who belong to a growing movement of Americans who practice polyamory — intimate long-term relationships with more than two people. (The polyamorous lovers in this story requested anonymity because of fears of discrimination from employers and even friends.)
Believers in polyamory estimate their numbers in the tens of thousands; the attorney general’s office in Utah and Arizona have calculated that up to 40,000 Americans practice polygamy, a form of polyamory limited to multiple spouses.
