I'm actually the guy running the site, so just thought I'd add my 2 cents :) With this site, the main focus is building a business model around Android development - "making money" with Android. That's not to say app quality has to go out the door. In my experience, you can't really build a sustainable business around crappy products. So it's in my best interests to keep up the quality, even if the business development is the stated goal (and the one I'll write most about).

Agree with you 100% that quality is key to success. I just chose to focus on the business & financial side of things, since at the time I started this blog there weren't many people writing about their experiences with Android.
