Where's the actual post mortem analysis? I wanted to see a discussion about actual problems encountered developing Tweagle specifically. Instead, this is just another exposition of the generic flames we've all seen done to death. Android apps have lots of screen resolutions (so what did you have to do to manage that?). "Some devices lack WiFi, A-GPS or both." (what is your fallback if the user doesn't have local internet or location services?).

I especially like this one: "Some people “hack” their Google Play app to be able to download incompatible apps and then write 1-star reviews when the app doesn’t work" ... with no discussion about why their app was marked incompatible in the first place.
