The current linkedin.com homepage clocks in at 1.9MB of CSS (156KB compressed). After re-building a fully-functional version of the homepage with CSS Blocks, we were able to serve the same page with just 38KB of CSS. To be clear: that's the uncompressed size. After compression, that CSS file weighed in at less than 9KB!
