I like the comment area of the rep because it lets the person know WHY I am giving rep, and if it makes me say "Wow" I find it easy(ish) to say why. My "Liking" something means that I like what was said/shown or that I agree with the statement so as not to repeat it in my own post.

And Faceplant (nice term Jax) did not invent liking something....although they might have "popularized" it.....so that shouldn't stop people from actually liking what they see or read....
