The demand is how to get the content of what you want and when you want in the quickest and easiest way.
Social networks, Tweets, FB, RSS subscriber, flipboard etc. all attempted despite the Ad revenue must be taken care along the way, yet none has really met the demand.
Do you get news from your friends, or subscribe people, or visiting sites? To me it is as much as mundane as 20 years ago when internet started. The problem has been resolved except many have made tons of money while tackling it. The fundamental problem remains unresolved and still waiting for answers.
