To most non-dev people, being hit with error after error when fixing one small problem out of a much bigger collection of problems would probably be infuriating.

To me, it's a huge loop of:
for(var failsAtLine = 1; failsAtLine < lines.length; failsAtLine++;) {
changeSomething();
runTest();
readErrors();
cry();
comtemplateMeaningOfLife();
}

openChampagne();

Would help if deployer.org had better documentation and bigger support community.
