One thing you must not do You have a job. You are paid for it, and expected to deliver. You cannot ignore your professional responsibilities and be on the internet for personal reasons, no matter how useful, during your working hours. Make sure that you use the internet only for work-related reasons when in office. Once you get back home and have time to spare, visit the social networking sites and use them meaningfully. When you are at work, in other words, never ever forget why you are there.
