Roadmap 2017 says steem.io is being updated.

Yeah, but nothing has happened yet.

For getting things done I think we would need to create a media production/marketing group, and use an easy system of communication. And also try to involve the community as much as possible

The problem has been that most users have made individual efforts or worked in temporary small groups. It's essential that we start to focus and centralize our efforts.

Involving the community is not necessarily a good thing. Many times a handful of motivated/skilled/active people can get a lot more done when they are not distracted by others. We can't use Steemit as a platform for this because here is too much noise. And it's also necessary to have notification system to inform all participants what is being done and when. But if there is a notification system that devs and whales use, it will be used for spamming.

So I think there should be a moderated group that is open only for those who are committed to work for the blockchain. Trolls, spammers, and people who can't respect others have to be kicked out before they distract those who are actually trying to get shit done.

Wider community involvement will come when there is actually something concrete that can be used and shared.
