It's hard to measure whether if it has added to the network or made it worse (we don't exactly stick to curating really good quality posts, going more for stuff that can be understood and looks like it's taken time to get produced. Sometimes we even vote on not-very-stellar posts just because the account has been consistent with their persistence). But still, I think it's worth it. Sure the "max" rewards for posts have declined in line with Curie's allocation, so instead of a few really high paying posts, it has been diluted to be spread to more than a few more accounts.
