Well, there is obviously a conflict in UI experience. I can very well see how back/forward breaks the idea of a web "app", because what would backward mean in a classical app, except for maybe undo? I tend to put web addresses in roughly these two categories: those that try to be an app, and those which just present a document. True, inline editing may blur the line, but thats how I try to see it. IOW, I am not mad at someone killing my back/forward buttons if these just dont make any sense in the context of the app they are providing. OTOH, I am pretty pissed if someone steps outside of classic HTML if all they are doing is basically prviding text/images.
