make it simple. stick with one chain, everything else is too confusing, steemit/steempeak is already super confusing for newcomers. makes sense to go with hive, ninja stake out, no chance of that stake being used to control the chain. that said a lot will depend on the workings of hive and if they can prevent a large stakeholder to control it. a lot of whales will be transferred there, so don't know how that will turn out.
