I don't have any use for errata myself. I can pretty much fake myself through any issues where errors suface in any book. I don't trust the errata anyway. If it's being put out by the folks who originally made the errors to begin with, how accurate can it be?
I make my own errata. If it matches the official errata then great. If not then it is obvious the official errata needs to be changed. I am the master of my own game.
If I see a problem in the rules, I'll fix it. If I don't see a problem in the rules I don't fix it.
It's probably a pre-intarweb mindset, when I think about it. Most of my RPG'ing life has been one where you buy the rulebook and never have any other contact with the company and/or its designers; mentally I still live largely in that world
I've looked for errata when something was so bad I couldn't make sense of what they meant, or if there was a blatant contradiction. Otherwise I don't worry myself about it, since I'm not likely to refer to the book, then check the errata to confirm if the book is correct. And I'm less likely to look at the errata first.
The main reason I don't like errata is because (for me) using it is more difficult (flipping between rules and errata) or tedious (crossing out text in the books and replacing it with the errata) than not using it.
If I'm going to the trouble of planning a game, I don't want to waste time with extra tedium. If it becomes an issue, I'll just make something up at the time. If there are too many issues, I'll think about switching to a different system (YMMV).
As a former US Air Force communications specialist, I am used to handwriting changes into books. Simple cross outs and careful printing, or pasting in blocks of text really doesn't bother me. What does, as I said before, is not having it available. I may not use the errata, but I want it to be there if I do decide to do it.
