I’m a huge fan of CSS preprocessors. They allow you to work faster, and smarter with what is considered frustrating limitations of CSS, and these preprocessors are influencing what will hopefully be baked-in to CSS in the future.

I still think I prefer SASS, for it’s feature set, and Compass. But it’s hard to argue that LESS is made more popular for two big reasons:

• It’s the default that comes with Twitter Bootstrap, the most popular frontend framework
• The toolchain to get going is simple – just include a JS file, and start writing your LESS
