5 Social Media Start-Ups You Should Work For

i'm just going based on the company descriptions, when I read LiveFyre's I thought "disqus" so, not very interesting to me, as it has been a solved problem for a while.

Where's the "self-driving car" start up? or the "Let's revolutionize higher education and put colleges out of business and save the world" start up?

all of these revolve around acquiring, engaging or making sense of web traffic. not very compelling if you ask me.
