Why didn't Google decide to instead contribute to Less or Sass I'll see you and raise: why didn't Less contribute to Sass? ;-) I don't see either question as being a problem in real life. You're going to have to have the build tools installed for any substantial web project you work on, and it's going to be less, sass, uglifyjs, closure, yuicompressor, the one I use that you've never heard of, or something else. Exactly which tools used is not particularly important. And if you look at the Closure Stylesheets docs, it takes about 10 seconds (literally) to get it, if you're already familiar with similar systems. And if you're not familiar with them, you're riding the learning curve no matter what system you choose. Finally, as to the observation, the argument is extremely compelling if you are deciding which toolset to use on your new project. Should I use Closure + Sass? Or should I use Closure? What do Less and Sass bring to the table that Closure does not? (I'm not badmouthing these fine projects, and would not fault people for using any of them.)
