> Possible Pros: You find out you are 20% Norwegian! Fun!

It's kind of irritating the way you are minimizing the "pros" here (and you aren't the only one at HN who has done this recently). There are people who found their parents and siblings thanks to 23 and Me. I found my father and my half sister. Maybe it's not important to you, but there are people out there who are willing to "pay" a lot to find out who they are. I appreciate that to you it may not feel like a good trade, but please have the empathy to understand that for others, it is.
