I've been thinking for a while now that Steem could have more than one blockchain. Each blockchain would have different reward system to encourage different types of content. The blockchains would be sidechains so that SD could be transferred from one chain to another.

I know that Steem operates with the assumption that it's bad to collect transaction fees from users. But an idea just popped into my mind: if somebody wants to have more than two reward payments for the post, he could have more by paying for them. If additional reward rounds increase the memory requirements, it's not feasible to allow them... but if somebody wants to pay for it, why not? Probably not that many posts would have more than two reward payments so the memory requirement would stay moderate.

What is the right path to making Type II content a first-class citizen in Steem?

Is it in any way feasible and reasonable to have several different content types with different reward mechanisms in one blockchain? It would help a lot if it was possible to help one kind of content without harming other types.
