Hello,
I don't know if someone already posted this video of Dan on Steemit but it's really interesting and very useful to understand how EOS works. Dan confirmed in the video that EOS will allow anyone to create Steemit like applications.
He also talked about producers, to be a producer you will need votes from the community but also a lot of computing power and bandwidth. Nobody running a node from his home is going to be a producer, be ready to invest in a robust cluster with a lot of bandwidth.
