LinkedIn, to me, is that social network that never dies.  (In 2007, I announced on Twitter that I thought LinkedIn was doomed – I am not afraid to admit it and I think many others agreed with me then).  Just when you think its loosing its relevance, it does a 180 and embeds itself, in some fragmentary reinvented way, into our professional lives.  So, given LinkedIn’s comeback kid-like nature, I thought I would post this infographic from Ellie Koning here, to show the networks now strength in our competitive social sphere.
