• Know that "sexting" is a term that the media has placed on the act of sending sexually explicit texts and photos via cell phones or online. Because it's been in the media so much, teens probably know what it means, but it probably isn't (or at least wasn't) the word they use. This might be a good way to bring it up with your teen. Ask him/her what students in their class call it. I have heard terms such as "hooking up", "phone sex", "booty call". Some don't have a name for it at all; they just know it when they see it.

• Use articles or news stories to spark the conversation. In recent months, there have been many articles about teens who were arrested for sexting. Ask your teen his/her opinion about if it is actually child pornography? What should the punishment be? Should it even be a crime?

For the first time in human history, technology enabled social media allow us to exponentially expand our network of weak ties, potentially into the thousands over a lifetime. In so doing, these tools dramatically increase the flow of knowledge and opportunity available to each of us.

Your Online Persona Can Help or Hinder College and Work Prospects

Imagine this: You've spent your high school years taking the most challenging course work offered, juggling multiple extracurricular activities and preparing for and excelling in your SAT's − all with the hopes of getting into your dream college. But ultimately you are denied entry for something you had never considered would become a factor: the content posted on your social networking profile.

This can and does happen. Colleges and universities are turning to social networking sites to learn more about their applicants. A recent survey conducted by Kaplan of 320 admissions officers from the nation's top colleges and universities revealed that one out of ten had used an applicant's social networking site in making the admissions decision. The survey found the social networking site could either benefit or harm the applicant.

Specifically:

? 25% of those who reported viewing applicants' sites said that these viewings had a positive impact on their evaluation; while,

? 38% reported that the applicants' social networking sites had a negative impact on their admissions evaluation.

(Read more about the study in the Kaplan press release.)

Content that had negative impact on the admissions decision included party pictures, underage drinking, reckless behavior, and fighting.

As parents it is our job to not only teach by saying but more importantly to teach by doing. By that I mean going beyond setting a good example by our everyday behavior. Teach by doing here means getting involved with what your child is doing online.

Our friends at ConnectSafely.org have outlined some great tips for parents who have kids or teens on the social web.

Be reasonable and try to set reasonable expectations. Pulling the plug on your child's favorite social site is like pulling the plug on his or her social life. Instead of being protective, it can shut down communication and send kids "underground" where they're more at risk. It's too easy for them to set up free blogs and profiles from anywhere, including friends' houses or even a cell phone.

Talk with your kids about how they use the services. They, not news reports or even experts, are the ones to consult about their social-Web experience. Help them understand basic safety guidelines, such as protecting their privacy (including passwords), not harassing peers, never talking about sex with people they don't know, avoiding in-person meetings with people they "meet" online, and taking care in what they post - because anything people put online can be grabbed, reworked, and used against them.
