It's a site that might become popular for blogging on EOS. It most certainly won't kill STEEM. What will most likely happen is a few big movers jump ship to gain as much as they can as fast as they can and the exact same thing happens that happened here originally.
We are finally moving in the right direction and can see new possibilities for gaming, tokens, communities and everything else that STEEM offers through it's fast and free transactions. I've no intention of moving as this is where I wan't to be and where I will be trying to wrk towards the future of our cryptocurrency.
