I don't understand the attention this is getting - sure, you don't need grunt on a lot of projects, I never start a personal project with it and only a fraction of my personal projects ever have me add it. However for work, it saves a stupid amount of time. grunt watch - that's enough of an argument alone for me to use it. Then add it in with a less compiler and live reload, and less now is magically being compiled to css and appearing in my browser a fraction of a second after I save a file. Sure, you could write a script to do that, but by the time you've got it working, you essentially wrote a grunt plugin, albeit one that isn't extensible and doesn't have a community of thousands of developers writing plugins and documentation for it.
