yes, I wanted to point that out too - but nowadays a lot of people use words Steem and Steemit interchangeably, something also mean community of users too.

as for biz model (aka "Ecosystem") it actually pretty much remains the same, or even becomes increasingly so and adds new elements to it (as RC). but certainly it would be good to get your sort of "revised" assessment of it anew. especially because you're still around since the 1st one, unlike many others who either left or became inactive (hibernating or lurking). so, yeah, please do that and perhaps I'll try to write one as well. :)
