Do you think the "crappiness of most apps" is because those apps were just too well-loved by their creators or because the people behind the app didn't care enough to do it properly (or even learn how to)?

Turning programming into mindless drudgery where you just go down a checklist of best practices is the reason so many programs are crap. The apps by passionate solo developers who really pour themselves into their work tend to be better than the just-barely-passes-tests work you'll get out of a cog-in-the-machine enterprise coder who just wants to go home.
