I used the word "personally" to clarify that I was expressing my own preference and not making an absolute generalization.
What I generally do is write web apps, and much of my enjoyment comes from figuring out how to creatively use other people's libraries and to write very DRY code.
The libraries I use abstract browser fragmentation away from my presentation layer, so I don't have to do endless run-debug-fix loops on the front end.
At this point, the code I write for each new project is 90%+ unique to the project and very thin, so I get to do the fun part of releasing and iterating it.
