This weekend some of the biggest names in social media sites like Craigslist, Twitter, and even Wikipedia met to discuss the issue of Internet dangers and "trust."

And while no one mentioned parental controls outright, the implications are that parents need to step up their computer monitoring.

ABC's local news piece on Internet safety and the meeting of some big names at UC Berkeley reports that Internet author and critic Howard Rheingold suggests that the "single most important danger" today is "kids who cannot tell bull from the truth."

What Reingold is more likely referring to is the host of Internet predators and online cyber bullies out there preying on unsuspecting or naive kids. It's a phenomenon recently termed "digital abuse," and can lead to child endangerment, child abuse, and in terms of cyber bullies, even suicidal thoughts and behaviors.

In response to Reingold, Jim Buckmaster, CEO of Craigslist explains that "that's where the parent comes in to protect them from the risks."

In other words, parental controls.

After all, how can parents know who is really contacting their child and sending those confusing instant messages? How can they see what sites are being accessed, and block websites that their kids shouldn't see at all?

Without parental controls, how can parents protect their kids from the dangers of the Internet, especially when busy moms and dads today have to work?

It's pretty hard. And while many parents don't think it could happen to their kids, it's fairly clear from the language of today's biggest Internet power-players that they expect parents to protect their children from online dangers
