So what literacies must we educators master before we can help students make the most of these powerful potentials? It starts, as author Clay Shirky (2008) suggests, with an understanding of how transparency fosters connections and with a willingness to share our work and, to some extent, our personal lives

Publishing content online not only begins the process of becoming "Googleable," it also makes us findable by others who share our passions or interests.

Although many students are used to sharing content online, they need to learn how to share within the context of network building. They need to know that publishing has a nobler goal than just readership—and that's engagement.

As Stanford researcher Danah Boyd (2007) points out, we are discovering the potentials and pitfalls of this new public space. What we say today in our blogs and videos will persist long into the future and not simply end up in the paper recycling bin when we clean out our desks at the end of the year.

Although Laura is able to connect, does she understand, as researcher Stephen Downes (2005) suggests, that her network must be diverse, that she must actively seek dissenting voices who might push her thinking in ways that the "echo chamber" of kindred thinkers might not? Is she doing the work of finding new voices to include in the conversation?

Here are five ideas that will help you begin building your own personal learning network. Read blogs related to your passion. Search out topics of interest at http://blogsearch.google.com and see who shares those interests. Participate. If you find bloggers out there who are writing interesting and relevant posts, share your reflections and experiences by commenting on their posts. Use your real name. It's a requisite step to be Googled well. Be prudent, of course, about divulging any personal information that puts you at risk, and guide students in how they can do the same. Start a Facebook page. Educators need to understand the potential of social networking for themselves. Explore Twitter (http://twitter.com), a free social networking and micro-blogging service that enables users to exchange short updates of 140 characters or fewer. It may not look like much at first glance, but with Twitter, the network can be at your fingertips.

. About 40 percent of the nation’s minors have access to Webcams, Carrill explained, devices for uploading live video to the Internet. About 65 percent of all children have access to cell phone cameras.Carrill’s team recently started a new operation to search image-trading Web sites for known child pornography in Missouri. The results were frightening, he said. More than 6,000 images were found in the state; about 700 of those pictures were downloaded in the Kansas City area.Between sexual predators who fish for images and immature decisions by kids with cameras, more children are either having their images posted online or being exposed to pornography, according to a 2006 report by the National Center for Missing and Exploited Children.

In the end, the best tool to defeat child pornography is parent education, according to both Shehan and Carrill. More than anything, kids need to know they can trust their parents.“It’s through that open line of communication between the parent and child that they can work through or prevent bad situations,” Carrill said.

All parents should follow a few basic rules when it comes to cyber safety, according to experts:- Keep computers in common areas of the home.- Monitor Internet use by children.- Enable privacy protection software.- Turn Webcams off or protect them with a password.- Track what images are being uploaded by children in the household.- Talk to children about what is appropriate.
