This is a very flexible way to accomplish A/B testing and since everything is hosted on your own site, you don't need to worry about any other variables finding their way into your tests such as additional load time. It integrates seamlessly with Google Analytics and can perform true multi-variative testing.
is there any specific reason that you dont link to the site [1] directly but instead use some sort of redirect using (possibly) your own domain (8n=hn i guess)?
I use Yourls on my domain to shorten and track links. I was curious to see how many folks would click through. It's my first comment here on HN (long time lurker). No real motive behind it other than just for fun to see if anyone cared what I said. I find myself hitting the "shorten" button the majority of links that I post online not only to see if folks are interested in what I've said, but so that if I make a mistake, I can correct it. 8n is just the next random sequence that was generated.
Of note, the Firefox addon LongURL (http://longurl.org/) is a great thing to have if you're at all nervous about shortened URL's.
