David Burt, who runs the "GetParentalControls.org," is one of America's leading experts on parental control technologies, and he has just released the Parental Controls Product Guide: 2010 Edition. It's an absolutely amazing resource for parents and academic researchers alike. I've spent a lot of time researching this marketplace and authored an ongoing report on Parental Controls & Online Child Protection, and I have served on several child safety task forces, including the new Online Safety Technology Working Group (OSTWG). So I'm quite familiar with the research in this field and I can say that this is one of the most important and useful resources I have come across in the past several years. Well done, David!
