Making each slide its own navigation event isn't bad, the problem is that browsers somehow still don't let you jump back to the previous website, not sub-page.
* myname.com/about.html
* myname.com/projects.html
Would you want to jump out of myname.com entirely when you press back? If not, how do you differentiate that from slides with myname.com/slide1, myname.com/slide2?
