Resteeming to me does not seem as effective as we might think, but then again I don't see it too problematic as well.
I may sound naive, but when reading that post from Dan and attempting to imagine in its entirety what the Idea was, it seemed to be that Resteeming was supposed to be a selfless act, kind of this is great information I love, more people should know about it. And maybe, just maybe by making it a service the altruistic element gets completely destroyed... I don't know, maybe I'm naive... but again I am of the philosophy live and let live..
