The site mostly works. You can set up an account, your profile, establish groups and mess with things. But some things might break right now too. Feel free. We need to find out what needs fixing. You can also post directly to Steem from your own blog in your profile, which will post to the community and provide for full integration as well (votes, comments, replies). Currently it's running the stock SteemPress plugin, so the beneficiary reward is 15% and all goes to them. That's the default and we'll be working in reducing it as we ramp up. That and branding are two of the things that will keep us from at least thinking that we're in beta. But it could be argued that the bells and whistles are there already.
