Cost Per Visit

Federal Computer Week has an article on the United Kingdom's effort to reduce the number of web sites the government supports. perhaps 75 percent of the 820 sites. They've also come up with a metric the US government should use: the cost per visit to the site. (The priciest was $17+ per visit.)  Although, on second thought maybe the metric should be the cost per minute of visit.  I've proposed before each government website should have a link to a set of metrics describing usage of the website.  I repeat the suggestion.
