So I love Flipboard as an alternative reading mechanism with a beautiful design for my Google Reader content. I also will peruse the imported social feeds. But regarding the social content, it's just very limiting to only view posts from my friends in reverse chronological order from the time I launch the app. I'm curious what content you're viewing on Flipboard +Robert Scoble
I much rather get a summary digest that uses logic to organize posts by my friends that are prioritized by how many of them linked to or shared similar items. This is why I use the Tweeted Times iPad app to fill that gap.
Lastly I use Zite because it has consistently provided me with content that isn't share by anyone in my social graph, yet is very good and I'm glad it provided it to me.
So these are 3 different use cases that each require 3 separate apps. Not sure anyone will nail all three of these together anytime soon.
