For home games, I have basically ignored most of these errata since they seem superfluous. Changes to things that were powerful in a single situation(and house ruled differently) or just completely flavorful(then made bland and useless). Not to mention in a home game a GM can rule a class works in any way she/he chooses, so a errata on non-pfs is a waste.
Overall i am happy they are looking at the books, even if they are doing nothing useful.
