The problem with working in a corporate environment is that everyone has Internet access, but few can be trusted. For that reason, many employees are banned from accessing eBay, social networking sites and even online retailers such as Amazon. However, chat clients such as messenger and Twitter are often allowed. Follow a few hundred people and you'll soon find that tweets are incoming quicker than you have time to read and follow the updates. Your boss will soon realise that you spend more time on Twitter than you do on your work.17 Apr 2009
