More and more often, parents ask me for a program that simply does one thing–manage their teen’s time on Facebook and lock it up after a certain number of hours go by. “We trust our child,” one dad told me, “but we know how easy it is for them to be spending too many hours on their Facebook pages and not enough on their home pages.”

Unfortunately there is no such program. You can buy software like CyberPatrol (pictured here) that limits the amount of time you can spend on the Internet, but not at one single website . You can use programs like KidWatch to create a log of where your children go on the web and see how much time they’re spending at a given site. Or you can use any one of a number of programs that would block access to Facebook altogether. GetNetWise has a good list of products that do all of these various things.

But what parents are asking for is a program that would limit the amount of time kids can spend on a single website, and, as best as I can tell, there’s nothing for them. Wouldn’t it be nice, for example, if your child were addicted to RuneScape, to be able to limit the hours spent on that site? Or to limit a Facebook session to 30 minutes an evening? Parents would have increased peace of mind. Kids would learn to be better managers of their time.

It seems like a simple enough program to create, so consider this a formal request to all programmers out there. Let me know if you can help us out.
