Just how harmful is Wifi anyway? Some folk at the BBC [believe](http://news.bbc.co.uk/2/hi/programmes/panorama/6674675.stm) that is is a pretty scary thing. Whether it gives me cancer or not, I can’t help but think that the biggest harm is the newfound ability to waste time surfing the net anywhere. But without wifi, I would not have found this [gem](http://www.wellingtongrey.net/miscellanea/archive/2007-05-27–the-truth-about-wireless-devices.html), from Wellington Grey. Of course, Canada’s own [Lakehead University](http://policies.lakeheadu.ca/policy.php?pid=178) (hardly home to luddites) is still largely wireless-free.


Dogbert knows a lot about oil, and perhaps more about resource economics than the average puppy.
