Well that was a bunch of useless information... "shoddy" code is in reference to code efficiency. If you write code that is prone to memory leaks, you write shoddy code. If you write code that has too many, especially inefficient, sql queries, you write shoddy code. If you write any code that has a negative impact on the server such that you suffer in experience, you write shoddy code.

And of course, I'm keeping this in the WordPress context. WordPress will never move to Java, .NET, C# no matter how compatible they are.
