I use LinkedIn. A lot. In fact, I suspect I'm connected to many of the readers of this magazine. I use it to stay on top of what colleagues are doing. Who is working for a new company. Who has gone out on their own. Who is posting something I'm interested in. I also post on LinkedIn a lot. Usually an article that I think has general appeal among my connections. Something on health reform, a new study on employee benefits, maybe the latest on digital health. The things I post usually come from various news feeds that I follow daily. And every post I make to LinkedIn also posts on my Twitter account.
