I think as writers we cannot completely turn off our editor brains and notice these things. As Ev said, flaws have always been around but if a story is really good, I'll keep reading, despite them. But I also think ems is onto something--most editors I know are spread very thin.
When I first published BOUND, it had a LOT of typos, this in spite of it being copyedited a few years back. Although I revised it again, I don't believe I introduced all those typos. So it went through another round of copyediting after publication and this is definitely something I appreciated about self-publishing--the ability to go in to correct those mistakes. I never want a reader to be pulled out of the story. So, lesson learned. Even though I'm good at developmental- and copy-editing for shorter works, I *need* a copyeditor for longer works like novels.
Melody, I agree. Good critique partners are GOLD. They keep me honest in my writing, don't let me get away with lazy writing, and push me to dig deeper.
