I'm sure there are multiple posts of Kier's that haven't received a like. I think I can say If i like a post from someone it'll get a like. I'm not into the habit of just liking any post because I'm either friends with a member that sometimes will get a like when it's not warranted.
I've seen posts get a like for the use of "lol" by members to their friends. A little odd but you like what you like.
