My app failed. I blame the App Store. It's easy to fall into this thinking. James points out that you should take responsibility when your app doesn't draw the attention you think it deserves. Blaming the App Store isn't going to fix your problem.
"just because you slogged through the massive effort it takes to design and release a product doesn't have any bearing at all on whether or not anyone actually wants what you made."
