RSS feeds

Explanation:

    RSS (Really Simple Syndication) is a method to get the latest news owners of a website. Through content aggregators you can subscribe to different RSS feeds that belong to different web sites. Thus, with this program you have centralized all the news that appear on the sites to which you are subscribed.  

  It's a way of centralizing all the content that the sites that interest you are publishing as a novelty.

    It is for you as a user not to have to go to all sites that have content of interest one by one to see what they have posted. You simply enter your RSS reader program and it connects with all the websites that interest you to download the latest news. Then, at a glance you can see the news that your favorite webs have published.
