May be they should have a demo for "The Slide" so that we can understand how it is useful to publisher.
Regarding the linkcurrent, I am not impressed. They have replicated klout score and have added number of FB likes & tweets and calculated some Number and called that as "Social Score" which doesnt sound great. May be its in a initial stage?
