"Like"

The simplicity of "Like" saves energy, but people often ascribe the properties of liking or favoring different things about the "Liked" thing to the action. What can be done with that without making it a compulsory 5-grade rating of 5 things about a comment?
I'd be OK with just an easily available description suggesting a common meaning. One word "like" is not enough, because it is not simple (for the lack of a context).
