Yes, that would also work to Steem's advantage. Do you have any specific / actionable tips or ideas on how to promote Steemit?
You can only tell so many people you know personally or are on your Facebook. Of course, one way would be to write posts here, since they also get ranked organically by Google, and this will help Steemit a lot in the long run, as Steemit posts will be near the top of search results.
