Not trying to advertise myself here, but I can be of assistance on this subject. If you are interested of course.
Frankly I would like to use such an opportunity to share with a large portion of the newbie c2p or f2p players a lot of tricks and tips which would ease their way into the game and not throw it away immediately. As for the rest of the community, I guess that even some of the older players could find some useful info here and there.
Your interviews offer some insight, but since they are mostly with p2p players, this severely limits the useful info they provide to the community IMHO.
