According to yahoo today the British government is warning its troops not to share their information on social media site for their security. Is that a risk to information on these sites? No it is not a risk as long as you do not share your home address or do not go to meet with someone that you don't personally know. Just the net is for fun, however there are billions of cyber criminals all over the globe. Do not give a friend that you do not know your phone number. Be captive, smart, and also ignorant to an unknown person. It is fun and safe on the net for everyone as long as you do not share yohr address and your social security number and some other most personal and important things.
