Well, I started the thread responding to a snarky one-liner that added even less to the conversation, so there's that.
I replied in earnest with a sizable comment comparing the two things (forums and malls) from several aspects (uniqueness, social function, etc), so that surely added something.
And, no, I'd say "signaling disapproval" does add to the conversation. In fact "signaling disapproval" is a large and necessary part of human conversation, and essential for forming social conceptions and hierarchies...
