Ryan Tracy thought he’d entered the Dark Ages when he graduated college and arrived in the working world. His employer blocked access to Facebook, Gmail and other popular Internet sites. He had no wireless access for his laptop and often ran to a nearby cafe on work time so he could use its WiFi connection to send large files. Sure, the barriers did what his employer intended: They stopped him and his colleagues from using work time to goof around online. However, Tracy says the rules also got in the way of legitimate work he needed to do.
