The way it works is quite simple: once you create a Flipboard account you can sync to your favorite social network (i.e. Twitter, Facebook, Tumblr, Instagram, and Flickr) as well as your RSS feeds of the blogs that your read or your favorite online news site.
It's all sent to you in the form of a traditional magazine. That means that, with Twitter, for example, if one of the web sites that you follow tweets a news link you'll see a picture and some text associated to it. You'll only have to click on the box to take a look at all of its content.
To go from page to page on your Flipboard you'll slide your finger as if you were reading a real magazine. The difference is, of course, that this magazine includes only the posts that you find interesting.
Flipboard is a very practical tool that will keep you up-to-date on the things that you like in a quick and convenient way. You only have to open the app (while having an internet connection) and start checking out all of the posts that you have chosen to sync to your account.
