I guess two things come to mind about that. One is to wonder if there's a better way to tap into the "otherwise would do nothing" people, more along the lines of texting to donate to good causes, though financial donations are something not everyone can do.

But the other thing is to frankly wonder about how much a person like that is really expressing an opinion on whatever topic they're memeing about, versus how much they're just parroting what their friends say. And I am bothered by that.
