Blogs have made such a difference in what we do every day. Take the site tripadvisor.com, which allows people to rate hotels based on their stay there. Clark loves to check this site before he stays anywhere because it's such a good blogging resource. And no one blogs more these days than our military personnel. They talk about all kinds of issues and topics on blog sites. But the military powers that be aren't too happy with this new trend and are putting the kibosh on it. Soldiers can't blog or send personal e-mail messages without having them reviewed by a superior officer. If they fail to go through that process, they can be taken to court. What Clark wants to explain is that people give up certain freedoms –- including due process –- when they enter the U.S. military. We'll keep you posted on what happens.
