I know that many blog readers are also big users of Facebook, and to that end, I've added a button below each post which will allow you the ability to share an NLM post on your Facebook.
I hope NLM readers who are also Facebook users will find this of use.
UPDATE: There seems to be some popularity in the idea of putting up a "Friends of the NLM" Facebook group, so that is being arranged and setup as we speak. I will make a post about it with the details later today.
Incidentally, if there are other networking tools other than facebook that readers believe would be good for sharing functionality here, do speak up in the comments.
