Hi! I'm the product manager who runs the Boost Nomination Pilot, and I just wanted to chime in here with two clarifications: Nominators are limited to two self-nominations a month, and can't actually Boost ANYTHING. All nominations go through our curation team, and there are consequences if a nominator's approval rating is low. Nepotistic nominations were an assumed part of this program -- that's why there are checks and balances built in.

Lemme know if you have other questions! I've written a ton about the program for the Medium Blog, and am always down to talk about it.
