First of all this is a monumental moment in Steem's history, the costs of running 3 year old blockchain will be cheaper than ever, I don't think many people understand this. Every blockchain that gets bigger over time is more costly to maintain, with MIRA Steem can be run by almost any PC configuration.
I have one question though, are there any bottlenecks left that would prevent Steem for massive influx of people, something that would potentially be another 1year development cycle problem?
I've always wondered about the whole 'logistics' of steem/blockchains; of course modern computer processing speeds are hard to even wrap your head around, I can't help but sometimes wonder how 'long term' feasible block chain technology is... I mean every three seconds there's more data to be processed. Admittedly I'm not a computer scientist and I'll leave this speculation up to people that are more informed on the subject. But I like what you're saying!
