2013 was a great year for the blog and for social media in nephrology. After a down year in 2012 for PBFluids, only 57 posts all year, I bounced back by nearly doubling that productivity with 112 posts last year. One of my most productive years. But to me the most remarkable change has been the emergence of a nephrology community in social media. My posts here at PBFluids certainly dripped with social media. Here is the year in review month by month.
