What is the difference between CJ and CJ2 sites?

What is the difference between CJ and CJ2 sites?
And what is a TGP/CJ2 site?

I am not sure of the ratios but I think CJ2 has to have a certain percentage of real free content (like pics on the site that are actually linked to big pics) while CJ is just plain old trade/link/popup hell.

anyone else know for sure?

cheers,

Luke
