I'm not sure if we really need a referral program. Steem is so freakin' awesome platform that it will market itself pretty much automatically without any added incentives. Things have just started and we are already the third most valuable blockchain.

I'm afraid that referral program might only cause a lot of spam instead of bringing something really valuable for the community.

If there ever is a referral program, I hope it doesn't give any rewards for new accounts that are created for free. It would bring too much fake users instead of real ones. Referral program should only apply to new accounts that the new user paid for (new account buying feature isn't implemented yet, but hopefully it will be soon).
