The Like, Reply links are unclickable when the mouse is directly over them.. but you can click them if you move the mouse a few pixels under each of the buttons.
I did a bit of checking, and this seems to happen whenever a post has a "xx replied to this" line under it.
For example, in post I linked, it says "rnovino and Duncan replied to this.".
