Information stress reduction tools

I was reading about life hacking (programmers productivity tricks) the other day and that made me think of the way we select, process and memorise information. It seems to me that the abundance of information on the Internet suggests the illusion that we can know and learn everything. However because of the enormous amount of information that is scattered over the Internet we will never be able to maximalise our know-how. What is lacking are these life hacks that help us to select and collect the most relevant information. Search engines help us to identify the articles, images or video on the net, but we still have to rank them in terms of importance, credibility and accuracy. Most of us do not have the time for that.
Therefore consumers and businesses rely on editors to select the information. The continuous increase of the number of magazine titles demonstrates that consumers value editors that can put together information relevant for specific segments. And it is the credibility of the magazine or newspaper brand that is the reason to believe the information.
Online consumers and businesses develop other tools: lists, social networks and referrals are the new tools to select and optimise their information need. I believe that the need for editors will continue to exist and that they can help reducing the information stress related to the information overload.
