They shouldn't give you stick for using a blogger at work - it's cheaper than a personal phone call, takes up much less time and you don't smoke so you're already at least 20 minutes up per day on anyone in the office who nips out for fag breaks. Plus it enables you to keep in touch with essential information about your main hobby, providing you with excellent work-life balance, which in turn keeps you motivated and switched on during work hours. Therefore by occasionally blogging, you are remaining a happy and motivated worker, always at your desk ready to answer phone calls and respond to work requests. As long as you don't abuse this privelege, there is absolutely no problem at all with visiting a blog during work time.
