Readness is quite a direct and understandable service. It takes the shape of a browser extension that upon being installed will let you read the news in a social way.
That is, you will be capable of knowing what your friends are reading at all times, and you will also have these articles that could appeal the most to you out of what your friends are reading recommended. This is accomplished by studying what you have read and who your favourite authors are – that is another asset of this service, it can build up a list detailing these authors that you happen to read the most. It can likewise analyze which kind of articles you spend the most time reading, and you can see the statistics whenever you want.
As far as using the site is concerned, note that not every item that you read will be visible to everybody. You can actually edit your list and delete these items that you don’t want others to see from your public profile. And in any case, there is a 15 minute grace period between Readness receiving a URL that you have read, and the URL being displayed on your public profile
