In July 2010 I wrote a very popular post titled "A Strategy for LinkedIn". In the post I recommended:
"The second feature I would add to LinkedIn is a Hacker News for business. Hacker News is a very simple site where people post the best posts on technology from a wide range of sources including blogs, corporate media (e.g. NYT) and white papers. The content is not moderated but the users create such rich content that I sometimes think that if I had only one RSS feed to read every day it would be Hacker News. A "Business News" on LinkedIn would bring readers to the website more often to post articles, would over time probably produce a better source of business information for the members than the automated sites such as Google News or Yahoo News and again could be a new revenue source for LinkedIn through ad revenue."
In mid-2011 LinkedIn started LinkedIn Today, member curated business news. I have been a reader every day since it launched and the quality of the articles is very high. I recommend it.
Probably just a coincidence that LinkedIn did what I said in a post, but if anyone needs a consultant to increase web traffic maybe I can help:)
