— SteemCN

That's great.

I was thinking of doing it this way:

First, let's hear some kind of acknowledgement from the biggest shareholders that the steem.io website is not satisfactory, does not match the current status of Steem and a significant improvement is needed. We just need the whales to acknowledge the need for action, nothing else. Otherwise it's hard to start doing anything when you're not sure, if there is any real demand for it.
Open up a competition to design and then maintain the website. This could also include redoing the introductory video. We already have all the resources needed: the funding & voting mechanism plus lots of creative people. We we just need someone like @ned or @dan or any other big shareholder to trigger this process (by announcing it) and then the process will take care of itself.
Create a new Steem tag (e.g. "steem-website-competition") and set a date when all proposals should be revealed under this special tag. When the date arrives, we have a vote, choose a winner and let her/him take over the task of redoing and then maintaining the website. Runners-up might choose to build their websites anyway, but the winner will have the privilege of being the official Steem website.
