Just noticed that a new contributor joined the ranks of Xbox.com.  Welcome to GamerDad Xbox Dad(not to be confused with GamerDad.com).

[Edit: I noticed they changed the title on the site.]

This new Xbox.com writer, Brian Johnson (Gamertag Brize), is the co-author of Xbox 360 for Dummies, so you could say he actually "wrote the book" for parents picking up an Xbox for their kids.  

Brian introduces himself in his inagural post:

...I'm going to explore the issues around kids and gaming that can make it hard to know if you're doing the right thing. This column is written both for parents and kids. I want to make gaming understandable for parents who might not be gamers. I would also like to provide the older kids with a parent's take on the concerns that we have around kids and gaming. This column will hopefully help parents make good, informed decisions about control and provide the kids with a way to understand those decisions. ...

...I'm going to tell you about the questions, discussions, and the disagreements (almost said fights!) that we have about gaming in our house and what we think is appropriate and what's not. 

...One of the major audiences we considered for that book was parents who don't know much about games. Duncan and I both think that gaming is good for kids in general and we thought it would be easier on parents if they had a guide they could go to to help them understand the Xbox 360, the games you can play on it, and how set it all up. (One business associate told me they should have titled it Xbox 360 for Parents.)

I mention this because I really want to stress how much fun it can be to play games together as a family. My mom and dad bought me a Magnavox entertainment system when I was a kid. When I opened the box, I didn't even know what a game console was. The console had ping pong, hockey, and handball, all rendered as big white lines on a black screen. My whole family played on that console together and we ended up spending hours and hours interacting, rather than just watching TV. I'll never forget that. ...
