The donate a book campaign is our way of encouraging users to share our app. Instead of spending $ on facebook ads, we figured we'd donate a book every time 2 of your friends download Zolt using your referral code.
The Shout feature is meant to give users another way to express themselves (in addition to the usual share on FB, Twitter etc). It's still a work in progress, admittedly.
Thanks again though for the caution - will be careful of avoiding feature creep.
However I still want an app that extracts only quotations and numerical information from the news and presents it on a table with a headline.
I think the app is nice to use, however I think it'd need to summarize articles of my choosing to be useful to me.
I found the landing page for the mobile app to be very noisy. Scrolling was all over the place.
