Takes this with a grain of salt, since I haven't done much more than dabble with J, but I've heard that it (and APL) basically forces you to carefully read and fully understand the code, rather than skimming, which is generally what happens with "easier to read" languages. And since it's so dense, you don't need a lot of lines of code to do most things.
