This is only somewhat related, but I find it really interesting that the vast majority of outfits using Sass opt for the SCSS syntax rather than the native one.
Personally I always opt for the latter, since I find it heavily reduces the amount of syntactic noise, which is a personal bugbear of mine. is the main reason for using SCSS the familiarity, or the fact it's a strict superset of CSS, or just that people generally dislike whitespace sensitivity? I can see the benefits, but it would be interesting to know if there's another angle I haven't considered.
