Ask HN: Advice needed re: adsense vs. adbrite

I built a site with a few friends over the weekend and it's getting some significant traffic. I'd like to maximize as much as possible, and I'd heard that Adbrite was a better choice than adsense, so I went with that.

2 days later, I've made 2.75 from 20 clicks in adbrite. a friend with a blog using adsense has 3 clicks and has the same profit we do.

am i doing something wrong? or does adbrite really suck? i heard that you need to somehow optimize and select ads in adbrite, but I wanted confirmation from someone on HN with solid experience.

btw the website is http://www.thathigh.com

thanks
