Goddamnit, I wish someone had mentioned "head-hopping" to me just a few months before I finished nearly 350 fuckin pages o_-
Luckily, I seem to have exercised SOME form of intuitive approach, when dealing with 3rd person POVs, since hopping from internal-perspectives are naturally confusing (you're delving into a characters thought-process after all), but I was not aware of how obsessively strictly some people regard this, like it's some sort of super-taboo. In one article, an example of an unacceptable head-hop is something like "Ben [pov] gave Bill [not pov, therefore we should not be privy to his thoughts] a gift, and Bill thought it was nice." <---kill it with fire? seriously?
I can't imagine reserving one POV per chapter, in a story where many characters interact, and different perspectives are important, and I did read about several methods of smoothly transitioning between POVs in for example hectic chapters that might require it - but even there, I've learned that some readers are just absolutely unforgiving - which I find just unreasonable :I
Again, thanks to having allready had some intuitive feel for keeping my POVs tidy, I still gotta run through everything, and do a little bit of sorting and tweaking, which I don't mind that much to be honest, I just wasn't aware how massively important something like this apparently turned out to be :S
