It seems like a lot of people are here to blog in some way, shape or form. These bloggers need an audience. Many bloggers use bots to auto vote, which is fine if they're doing it to support the author's they like and lack the time to do so manually. The blogger is either working on their next presentation or away doing other things.
A proper, fully functional curation reward system marketed to the masses is a great way to encourage an audience to show up and participate. A good incentive.
Unfortunately, I don't have time to repeat much of what I've been saying. If you're curious as to how I feel about it, have a look around the comment section.
