K just be careful. So far it's gone mostly unnoticed and most people don't seem to mind (or are totally unaware because they don't have notifications on for their name) I don't want to see it all fall apart in one moment's notice when one of these authors isn't happy about the idea of you making money off their content without any financial compensation.
Just takes one person with a big reputation or connection to a bot who from then on downvotes everything. Even steemcleaners or something similar to that.

I'd look into a more sustainable economic model where you give them some form of cut for being part of the content and also like many of these curation things do make sure to mention that if they don't want to be included that you will remove their content.

I think most of the authors realize the financial reward won't likely be large but it gives them incentive to support and promote your idea. Also seems you pay for a portion of it so that does make it a bit more difficult to figure out
Power up that account to get a better vote will also help out.

Good luck to you hope it goes well.
