These day. I joined in twitter and Facebook. And I watched many funny video clips on YouTube. Yes. I admit. These social website are intrigued. Why teens loved to spend much time on browsing. Scanning and commenting. Because each if us is individual. I found close people would like to share and comment on ur stories. And microblog. Cuz yours has common hobbies or same experience. We obtained follower. To increase ours confidence to build up ours own webpage. We put ours own feeling on it. We randomly record ours lifestyle. Via network. We get useful message from others. Such as one of my friend. Which lost his graduate certification. But he eagerly need it for interviewing in a recruit. He even couldn't get a clue. At present. I shared my pics of my school certifications. Via social website. We shared it public. Lastly he got my photo and called me back. I dealt with it soon. Yes. Via social net. We know. What is u loved. Ur innate feeling. Of disadvantage. You put everything of u online. Ur background. Which may lead to crime. And lots of unknown men spoil u by impolite ways.
