One aspect this piece doesn't mention are unit tests. I've found that writing short to-the-point methods helps with testability(?). I just wrote some unit tests the other day for a 100+ LOC java method. 300+ lines of test code to setup the massive amount of dependencies and go through all of the if- and for- statements. Would've been a lot easier if it was broken apart into smaller discreet units.
