Paleo??

Is anyone out there doing Paleo? (I realize this topic has been brought up before, but I can't find many people who are actually doing it). I have been researching for the past 2 days. I did atkins several years ago and not into doing it again. I know paleo is similar to atkins but not quite. Do you count calories on this diet? I cant seem to find the "rules" anywhere. I can find what to eat and what not to eat, but thats pretty much it. Can someone share their results with me? I am very interested in this. If anyone has any reading material websites I could take a look at please post them for me, thanks
