Maybe it's lost on a lot of people why Zuckerburg set up the like button. It's like here a lot of times that I'll hit on someone's post because something in the heading, or the few describe words showing spike my interest but not everything someone writes about will have the same effect. Sort of like the uncle that post his fishing pictures up every time he goes fishing, unless he snags and post an unusually large fish picture, or falls into the river or something unusual to that nature, you really honestly aren't that interested in another picture of a bluegill, so you hit like instead of a comment. On the other hand, if he sees you never ever like a thing he post, he'll figure why bother with her, she hates everything and off your list of family, friends, acquaintance you go.
