Fucking hate the people that insist on using only half of the number as if it was a real value. At least say you are working with natural unities or something.
Using "+1/2" and "-1/2" as vector labels is fine. Using it on the context of "the spin can have those 2 values here" for laypeople without further explanation is just making the subject less accessible.
Also, yeah, I was too lazy to search for the unicode ħ.
