In February, for the first time, Facebook sent more readers to PBFluids than Google. I believe this is from the ASN Kidney News now linking to my posts on their Facebook page. It'll be interesting to see if the trend continues or if it was a one month aberration.
In response to the increasing importance of Facebook to my readership I have created a PBFluids facebook page. A new experiment with this medical blog unfolds. Exciting.
