piercms site doesn't show _s and _k vars?

i just noticed that the piercms site doesn't include the _s and _k vars when you navigate around the site. am i totally missing something on my sites? i noticed that all the other sites out there behave like mine.. but it would be great if mine would have cleaner url's. this would allow me to use url shorteners at will, without having to remember to cut them down.. i also wonder if i am somehow missing out on some juice because as people trade links to my site, they _s and _k force the url shortening services to treat them as two different links. so while on bit.ly, for instance, ten people could be sharing the same link to your site, it would look like ten different people are sharing ten different links and skewing the stats. any ideas? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101
