Results: In this graph we can see an immediate 25% decrease in the bounce rate. The orange line shows the bounce rate is know skewed due to an increase of traffic at the site launch. The blue line shows the drop in the user bounce rate. I attribute this improvement to the sites navigation improvements. Visually the navigation is broken up into two consistent visual elements giving the user a familiar tool. Functionally this site improves the user experience by showing state in the address bar and having working forward/back buttons.

This graph compares the average time on site "Orange" improved by 2 minutes and bounce rate decreasing by 25%.

What is a host file? Lets say your editing website locally and would like to bypass any security errors caused by the localhost url. You can use the host file to redirect the real url "www.jonathanspooner.com" to point at your local copy.

I also added a short cut to my profile document so I can just type 'host' in terminal and TextMate will open the doc.
To do this create a file named .profile in your users directory "/Users/yourusername/" and bash script like the one below. I have a few other handy shortcuts in there too.

alias host="mate /private/etc/hosts"
