We choose 5 of the best recommended posts.
Here's the math:

Let's say a newspaper earns $300
Steemit naturally splits that up as so:
25% to curators
37.5% to author in SP
37.5% to author in SBD
The SBD earned is what's being rewarded.

Let's take the example of $300. 300 divided by .375 to get our SBD amount which is $112.5 SBD
Since we choose 5 winners who recommended the featured content, 112.5 is divided by 5. Which equals 22.5 SBD.

The reward is 22.5 SBD for that newspaper. 5 people win per day for recommending the featured posts, and we have a new newspaper every single day.

This is already in action and it's worked out perfectly. We just don't have the earnings we need to have a good incentive. But once we do have that incentive, more people will recommend posts, which increaes competition, which increases quality. And when you have a place where there's a ton of valuable content, everybody wins. Readership increases, and a community is built.

Not everybody wins rewards for recommending posts, everybody wins for having a place where high quality content is in abundance for everybody to see.
