I actually propose that we split accounts into two kinds: 1. On-chain accounts, 2. Off-chain accounts.
This works for Minds.com, which I believe is kicking our asses right now. At least, they are getting Youtube idols like Tim Pool...
Some things are just changes to condenser rather than the blockchain. Follows, resteems don't really need to cost RCs, and we could have off-chain comments that can't experience financial rewards.
This would allow the wider traffic to engage but still not be fully involved. Its like window shopping, and many people might jump on board eventually that would have been scared away by financial investment requirements.
It is kind of like how Medium does things. There is public Medium content and then the content that requires you to be a paying member to access. After seeing others get $0.08 all the time for just saying "your content is awesome!" maybe others will be willing to cough up some dough for a little STEEM.
