I can also reply to articles by re-tweeting, sharing, and emailing. It really does bring all of your social networks together in one easy location. Check out all of the the things you can add. It has different subject materials, so you can add topics that Flipboard collects based on that topic. I add some tech topics as well as sports topics. It even allows you to add hashtag searches, so you can bring in those Twitter topics you are keeping close tabs on.
The nice thing is that you can control it all. I really think that anyone that owns an iPad should take advantage of Flipboard. It is one powerful app. Download the app here and give it a look. I think you'll love it.
