Not a good sign for ETH. They depend on their main competitor website to explain what is Casper... It would be better if it was on the Ethereum website. Ethereum foundation website did look better in 2017. The website is faster to load now, but not very good looking.
What is your mean who is dependent to that website? Actually you need to make some research about this article there is nothing wrong if it appear on Binance's website it is like new dictionary for blockchain related projects.
