Worth noting is that there are two versions of the interview -- a short version, about four minutes, at the top of the article, and a long version, about 22 minutes, at the end of the article. They're both decent, but I found the 22-minute version the more worth the while of the two.
It's always encouraging to see a positive portrayal of polyamory (and other responsible non-monogamy), and this was definitely one of those portrayals. The interviewer was positive about it and the interviewees had great things to say.
I suppose the next step in the world's dialog about poly is to talk a lot more about how it affects the kids. I know of several poly families where the kids do/did just fine, but I also know of several poly families where things didn't go so well. It seems to be a growing concern on Polyamory.com at least.
So I think we need more dialog about how to make sure poly isn't bad for the kids. We shouldn't just assume that it'll automatically be good for them. There's got to be a few lists of do's and don'ts we can come up with.
I don't mean to get us all off-topic though. It's a good article and a good interview, well worth the time to watch it and even a good way to introduce newbies to responsible non-monogamy.
