-accepts uncritically gobs of code dredged up via Google
-considers something "robust" if it doesn't break old code, when the rest of us hate it because we have to live with register_globals and other horrors
-considers "universal support" of craptastic versions of mod_php to be a good thing (some, but not all, major shared hosting messes use FastCGI)
-modifies files in production and thinks that's okay
It makes those of us who do know what we're doing and focus on disciplined code look bad, because the article author is what most people think of when talking about "PHP programmers".
