A lot of people here want free access to the data without having to use a private key or register for their service. That's exactly what I told them recently and I won't implement any UA-Data (as they wish) as long as that is not the case, but there are a few more things I take into consideration. A more professional/human behavior when speaking to other people on the platform is one of them.
They call it a DApp, but it's not, because it is not decentralized. SteemWorld also is no DApp, therefore I don't promote it as such. To be honest, I'm currently not sure if my delegation to their service will stay for much longer. I have a bad feeling about the whole thing. For me it's a voting service without the need to make a transfer to receive a vote, not much more.
The rich become more rich, even easier, faster and more hidden than before, minnows receive a few cents and will be struggling with a low ranking for a long time. Most of the people with the highest ranks are at the same time the ones with the highest income and the ones that are not may find a way to build a fake network to push themselves up. I think it's nearly impossible to judge all people through a fixed algorithmic formula. Maybe I'm wrong, but I will stay cautious.
