Another (see here) little Your News Feed suggestion:
Or... at least move the link underneath the username ('Mike') to underneath the word 'post', because it is about liking the post. Not the user.
Since it makes the username a link here as well, you also untuitively expect it will go to the user's profile. But it doesn't. It takes you to the post of that user. It's a little thing, but I would make 'Mike's post' a link (including the word 'post'), so it is clear the link is connected to the post, instead of the user
