As an affiliate marketer i need to track all the click on my links across all the websites... i investigated in Goo.gl and Bit.ly solutions but i wanted a hosted solution. I found Yourls an open source shortener and Prosper202. I use Yourls with a Google Analytics plugin on my own domain name www.jeclic.com and i can see all the click as page view in GA, i have interesting detailed reports :)
