The digital "tut" is perhaps a inter-social-media protocol we could create. Like a downvote, it indicates disapproval and starts trying to, as this article persuasively says, move social nuance online. Twitter, Facebook et al could all have this alongside a like button, on a RESTful interface so it's agnostic about the client. Many, many years ago I stumbled across a web page hosted on a white supremacist site but was third in google's ranking for Martin Luther King search term. It struck me then that what would be useful was not for me to link to that site (hence adding to its pagerank) but to link to that site with an href attribute that indicated something was wrong about the facts presented. I think overall this is the same problem of short selling - and it's not clear how to fix it.
