This is an interesting move by LinkedIn and will place it more squarely in competition wtih HuffPost, Mashable, and frankly, with sites like ours. Sharmin, you are absolutely right that LinkedIn can reduce the noise by embracing community, but community, if done right, is difficult to scale and hard to maintain over the long haul. (I know; this is how we've been growing Social Media Today for some time.) Also, "user-generated" implies that they do not intend to compensate their posters and increasingly, we have found, along with HuffPo, Mashable and others, that having quality content on a sustainable basis means you may have to pay for it.
It will be interesting to see how this rolls out from a user-expereince standpoint. Will users find the content experience sufficiently valuable to give up enough of their behavioral data to make it an increasingly valuable experience? Will LinkedIn, whose latest results were a disappointment to investors, be so intent on monetizing this new move that they undermine the value of the content even further?
Clearly, this will spook sites like the above-mentioned as well as BusinessInsider and WSJ. But we shall see how well this is executed.
