I would say integration is also very important to Steemit. Not discarding the need to continue providing a better blockchain for Steemit, but in parallel doing integration is key for a wider network to test new limits. Integration goes like other social media networks. The easier it gets for others to use, the more likely is the technology going to be explored and improved.
I would love to see integration with Crypto Cards (Credit or debit), decentralized exchanges and decentralized frontend. If steemit.com is down, there is little left to do with the blockchain, with the exception for all the other apps/software that use the same chain.
