This article focuses on social media and has tutorial videos for Twitter and RSS readers. Almost all of these resources are free. Users can be overwhelmed because, like primary journal articles, they are now proliferating exponentially. As far as I can tell emergency medicine physicians are the leaders in the promotion and adoption of this technology. Despite that, recognition by academic medicine remains poor overall.
There is a lot of discussion on how to organize and vet these resources but nothing is settled. This is nothing new. In my nine years in the blogosphere I have seen many such efforts come and go. Nothing will ever be settled except for this: caveat emptor. Ultimate responsibility lies with the user. It's a jungle, but so too with books and journals.
