Time for my second iPad app recommendation. Flipboard seems to get all the love yet, while I do use it, I find myself looking at Zite much more often. While Flipboard is source oriented, Zite manages personalization using topics. This generally works well and provides a more diverse mix of stories than Flipboard. Zite takes personalization another step further by allowing you to give a thumbs up or down to a story to help guide which ones it presents to you in the future. You can also indicate a preference for certain sources as you page through stories.
Navigation is easy and the usual methods of sharing stories present. I like it’s Twitter integration better than some apps because it uses what you’ve configured in Twitter on the iPad. I have a couple of Twitter accounts and Zite lets me pick which one to post to on each share.
