I'm not bashing anyone who does do it, not in the slightest, I know it's helpful to the site in a way.
But sitting here set-surfing, and a thought crossed my mind... do people actually click "not for me"? (The option next to the like button on a set?)
Me personally, if I'm not particularly enthralled by a set I just move on to another one. I've never in my life chosen "not for me" on a set; as a Hopeful I personally don't want to feel like I'm deterring other Hopefuls, especially since it's always a preference thing. I feel like not giving it a <3 is enough for me.
It just makes me wonder how many people do actually choose the "dislike" button on sets. And how many times it's been chosen on mine. :p
