This give a whole new meaning to being a "Steem plankton", and it was something i remember talking about in one of the meetups i had with some Steemian friends here in Malaysia.
I'm all for it. Makes sense since it incentivises newcomers (who are ussualy excited) to engage and earn upvotes. those who can stay are those who put in the work since there is a price in registering an account.
Had this been implemented just a year prior, i think the steem community today would end up way better than it did.
