I would like to say that
Google Analytics is awesome, for one it's made by Google so it automaticaly rules, second it's free, and third it's powerful.
It's invite only and it's pretty hard to get an invite, it took me three weeks to get an invite and they sent me two invites. I am giving the other away but if you want it you need to show me your site and prove that you actually need it, because I don't want to give it to someone who it going to use it on their xanga or myspace or some crap. Just post here or let me know some other way.
