Huge fan of this idea so first off - thanks for running this @
benkalashnikov! Overall I think it's structured quite well. One thought I had though is whether you'd consider randomly picking a "minnow" to share in the profits of the fans too? You could set a rule that they need to upvote or comment on at least 75% of posts, etc., but that way it encourages minnow involvement too (and will help these series of posts continue to trend up), as opposed to automatically benefiting the dolphins/whales.
