Was reading sass vs less on css-tricks. It really felt like compass gave sass an edge on the battle. A few days ago bootstrap also released a ported version of sass which is quite nice.

Kinda of off-topic, but I found codewars to be pretty interesting. Interactive code challenges, differ itself from the more "tradition" way of coding. I wonder is lessons like these will one day be implemented as classroom work? Hopefully one day it will happen.
