Totally agree with your views on this. I think Justin is not only more driven than Ned, he's more savvy than him.
Like you said consolidation is not always the answer, and we see many large corporations acquiring smaller interests, only to carry on running them as separate entities. Coca-Cola buying up Innocent Drinks comes to mind.
However Steemit does need to be changed if it is to thrive, so let's hope he has a plan or three up his sleeve!
