I believe that as Steemit grows, its popularity will spread largely by word of mouth. I, personally, heard about it from a you tuber who my dad was watching, who talked about cryptocurrencies. However, as the community grows, it will naturally begin to feature in google and other search engines, which will bring more people into fold.
Let God worry about the growth of the project, as he takes care of everything else. ^_^
Agreed. Amen! Since you're new, here's a user-friendly guide to Steemit I put together that you may find to be helpful. God bless!
