I'm working on the idea of creating an auto-aggregated news site based on Steemit-post with in the "news" tag. In short, it will just be a very limited version of Steemit, but with some pretty extensive quality control algorithms.
I got inspired to create this, because news these days seem to be driven by sensationalism rather than truth.
Since the site will work as an interface to the Steem-blockchain, readers have access to the same info on the writers as we have on Steemit. The site will also state clearly that it's based on Steem, thus sparking an interest for Steem in the reader's mind. The question here isn't necessarily how this will help Steem, but rather how Steem will help the world.
The project is in its really early stages (I'm still familiarizing myself with the Steem API), so at the moment there is not much to upvote, but who knows, one day...
