Who make up the swarms that gather round, eg, http://theaimn.com/2013/03/03/nothing-to-lose/ & The Conversation? Does every additional comment to the list devalue the medium?
What will fill the gap opened up by social media? Anything in common between readers of Dolly etc and Facebookers? Sales of car mags? Is it broadsheet readers who’ve migrated to online? Will they go to tabloid format?
