I think the criticism of "concrete" is well founded-- liberties with abstracts do not make them concrete.
As far as overall criticism? I think you are trying to nudge a different translation; but you are free to feel that way obviously...
Taking a tour would not change my position as I do not have the issues others have with the P2O concept/process. The only thing that would help would be to have the harder questions answered. I've been down the road of visiting and conversations before... closest I ever got to satisfying "issue resolution" was not allowed to be shared openly.
Given that, I prefer the objective separation, but do not recall criticizing anyone just for deciding to do more "hands on" research.
