Steem is imo the most "democratic" blockchain that has been developed until now, we're attracting a lot of people of the third countries because you don't need money to take part in it.
We often tend to overlook the importance of this, here is easy to fund solidary projects of all kinds, to develop apps that benefit many people on their lives, Steem is still a marginal blockchain but I don't see the same potential in other blockchains where you need a lot of money to invest in.
Obviously this have some counterparts, there is zero interest in the goverments and banks to support this kind of tecnology, mainly because this could easily undermine their bussineses.
If Bitcoin is revolutionary because lowers the power of the banks imagine the potential damage that this blockchain could do to them. We all have to expect an extraordinary resistence against Steem.
We tend to write a lot about technical aspects in which I don't have enough knowledge to discuss but don't underestimate the political and economical aspects of this blockchain.
