One of the things that I find very interesting is the lack of community interest in errata. There was a lot of discussion about the errata push when it was first announced, but no one seems to care now that 4e has been announced. I find it very strange that people in the 4e forum will argue to the bitter end about what "clues" were given about 4e, whether WotC officials gave misleading information about 4e, discuss business models, and scour blogs for more info, but formal news releases and direct posts from WotC employees about errata have been pretty much forgotten.
People screamed about the magazine cancellations, but aren't bothered that WotC will charge them for errata via Compendiums or "deluxe" editions, and will lie to their faces about it. I have seen many people proclaim that they will never support 4e because of what WotC did to the magazines or campaign settings or their favorite sacred cow, but no one complains about the lack of errata.
I just don't get it. Maybe it's because I work as an applications engineer, but I believe that post-market product support is a huge deal. For me, it's a make-or-break consideration. But it seems that I am the in the minority.
