People posting anything that is good advertisement for steem/steemit/busy.org outside of those three places can make quite a bit of money. I believe videos are the best mechanism for that. I could make some but I am slow at it, and there are others like @stellabelle, @mrwang, etc who make videos all day long. I am just trying to inspire them. ;)
They'll get the money for making the advertisements, but all of us will benefit if a lot of people adopt the platform. Even if they adopt it for something other than steemit.
