Actually, Flipboard is one of my favorite apps, whether free or paid, and the one I use most often.
I love the way the app displays twitter feeds like a virtual newspaper, taking the links tweeted and displaying the first part of the article so I can easily scan it to see if I'm interested in viewing the whole thing.
From Flipboard's description in the App Store:
Named Apple's iPad App of the Year and one of TIME's top 50 innovations of 2010, Flipboard is a fast, beautiful way to flip through the news, photos, videos, and updates your friends are sharing on Facebook, Twitter, Google Reader, Flickr, and Instagram. See your social media in a magazine layout that is easy to scan and fun to read. Catch up on the latest stories, videos and posts from popular publications and people such as National Geographic, The New Yorker, Wired, Rolling Stone, Oprah, Forbes, Robert Scoble, and Brain Pickings' Maria Popova. Share articles and photos, comment on posts, and like or favorite anything. Customize your Flipboard with sections created from your favorite news, people, blogs, and topics.
Well said. I know this might sound like a paid advertisement, but I'm not receiving anything in exchange for this review. Truth is, I was going through my feeds on Flipboard and having trouble coming up with a story or topic that grabbed me when it came to me: Blog about Flipboard! It really is, for me, a killer app and the unbelievably great thing is that it is free! Something that is important to me as a starving artist. :)
