Totally in agreement, the barrier of the language is a problem in steemit, for the present 90 % of the content is in English and it provokes a rejection for the people who does not speak it.

The second barrier is that there are no whales that speak all the languages, as what to the people it does not have interest in postear in these languages. (I imagine that it will change with the time, but to the step that we grow it will be in a lot of time)

Maybe a translator of page, who translates all the post into the language that your you use can be the first help.

Here we have a graph on the languages of the world.
