Sounds like a good plan. I noticed you said beneficiaries and was curious how you'd get around the 8 account limit. Sounds like something worth increasing on the blockchain level (it's come up before as well).
I imagine everyone who gets tagged on a winning post will vote it up as well. Kind of like a self-payment from the rewards pool for winner. Can't say I blame them either. If I won a tournament and my name was listed in the post that's going to partially pay out to me, I'd probably vote it up also (even though I don't self-vote or use voting bots, which are just another version of self-voting).
I'm excited to see where this project goes. Good luck!
I've read somewhere that Steemit INC is planning to increase the beneficiaries limit from 8 to 256 in one of the upcoming hard forks but I'm not confirmed about it.
You're right about the self-upvote thingy. That was one of the reasons for saying that winners vote list is expected to trend more often than payout posts. But you described it better than me.
Thanks. I'm also excited about the project and your delegation should start pumping the things up now. ;)
