A member's tally of Likes can be informative. Suppose you're new here and you ask a question. Your question is answered first by Person A and next by Person B, who gives the opposite answer. Person A has 200 posts and 30 Likes. Person B has 10,000 posts and no Likes. Whom are you going to trust?
As tandemhearts said, a Like can replace a "+1." It saves a post that way: less scrolling, less time spent. It can also replace a post that says nothing but "Nice shot," and those are numerous.
