Yes it would be pretty easy to make a sharing platform like Reddit with I something like steemit, but do we really want that? I at least think that steemit is much more valuable because the content is more valuable (in a lot of ways), and I believe it is just a matter of time and maturity before most quality content will be made here, pushing even more of the traditional medias out and under.
We will see if course, but I am hopeful ^^
