AJN (the American Journal of Nursing) just posted their April issue online, and I have an article on FOAM in there. You can read it here if you're a subscriber.
What is FOAM? The obvious answer is to read the article, but to whet the appetites of all nurses (particularly educators): FOAM is free open-access meducation (or medical education). It may live and prosper or die off, but in some form it will go on to transform the way nurses become lifetime learners.
I can't provide the full text here, but please check it out and let me know what you think.
