I like the overall treatment to this site design. It feels a bit like Microsoft esthetic (but better executed) which is just fine and looks great here.
Microinteractions
Microinteractions are subtle site animations enhancing engagement. They include triggers, rules, feedback, and sometimes loops/modes. Practical uses: improving engagement, guiding user behavior. Well-designed microinteractions boost user engagement and your online presence.
You can tell how great they are by all the ribbons from other sites they tacked onto the side.
Those drive me crazy too man.
