Thank you @cryptictruth. You're right. Figuring out all the details about steem platform is hard. I'm going to follow the recommendation of an old joke and assume the cow is a sphere. In this case I'll assume Steemit is a blogging platform. I don't think I'll use any of the links for now but I voted for your comment because I thought 'Wow! You can do that with steem! That is crazy!' For now I'll do what @steemladder suggested and read Steem Blue Paper carefully.
