I'm pretty sure we are dis-agreeing.
We'll take it by numbers:


1) I forward the idea that IMO a person needs to have experience in publishing nor marketing in order to make the claim that they know how to successfully publish.
2) you present Andrew Rollings as an example of a person who writes about publishing without publishing himself.
3) I say he has the experience to write the books he does
4) you counter by saying he hasn't published any games
5) to which I agreed because he writes about game design and not publishing nor marketing; Hence he isn't an example of a person who is writing about something without having RL experience in it themselves.

So here we are, me repeating myself and you pissing on you leg
