I agree with you completely on this. Steem.com should be the landing page for the Steem ecosystem and that should belong to the community. Steemit Inc has their own website in Steemit.com.
We need to take that over and let the community developers structure the site as the community sees fit. This could also tie into community marketing.
The ecosystem needs to break away from Steemit Inc on many fronts: this is an ideal place to start.
