What is the definition of "porn" in "one in five men admitting to accessing porn at work"? I'll freely admit to having looked at an image of a scantily-clad woman at work (from a major news outlet of all places), but is that... "inappropiate material", "porn" or what?.. I can see it being brand damaging if (female) customers had seen me watch it. I don't get how they reached the broad-sweeping (and inaccurate IMO) conclusion:"The merging of the home/office world is complete." and "From personal e-mails to social networking and downloading porn, individuals will continue to exploit the corporate network for personal use if they can" ("exploit"?). I try to keep a degree of separation between work and home, and I believe most do the same (though "home" can be the laptop I bring with me to work) - I don't use my work PC for downloading porn or dating - I do use it for personal email or some kinds of "socialization" like HN.
