Yea... no
I'm here because of the possibility of meaningful, interesting, or just plain old entertaining discussion, not to participate in yet another of the popularity contest cesspools that seem to have pretty much taken over the internet these days. From youtube to twitter, far too many people put too much stock in what pleases the faceless mob (and/or gets them pissed off in some cases), and far too little in their own thoughts and ideas.
If you wish to show your appreciation for a post, it is entirely possible to do so while making your own contribution to the thread.
