We need better ways to access and engage the blockchain. I'm using esteem right now on my phone but I find it clunky and not intuitive.

We also need to make everything accessible to people with disabilities, access and functional needs.

Better sharing mechanisms to be able to share content between platforms. I'm on three other social media platforms, none of which can share to or from steemit without copy/paste.

We also need a form of active curation so that new people don't get overwhelmed with the shapeless mass that they encounter when they first start. We need a guide to good content, otherwise people get so overwhelmed with the crap posted by some people that they just quit using the platform.

Just some thoughts from here...
